You are carrying me through college-level algebra. Thank you very much
this is college level?? im learning this shit in 11th grade
@@tzuyu8788 Well I was doing this while in dual credit in the 11th grade, so meh. Last semester i was an 11th grader.
I'm doing this in grade 9
@@tzuyu8788 its reoccurring topic, I first learned it in 7th grade when taking alg 1 then alg 2 in 9th and now I’m in 10th doing college precalc and reviewing it

IN 8TH
If I was a millionaire, I'd hire you as my private tutor.
Lol
Lol 😹 I'd also hire him. This guy literally knows everything
After Eminem obviously 🤧
Probably YOU r
@@simphiwebling9092 what do you need Eminem for anyways

Instead of reviewing my notes, im watching every video for every section im gonna be tested on lol. Your explanation is so easy to understand.
THE FACT THAT THIS MAN MADE A VIDEO 7 YEARS AGO N IS HELPING ME IN 8TH GRADE RN TYSM
I used this video when I was in 8th grade too and now I'm using it again when I'm a junior in college so it's crazy how he has helped so many people throughout time and continues to!
Bruh literally first 4 min did better than a weeks worth of my teachers teaching
hi, for the domain of the third graph, shouldn't it be 4 instead of -4?
나도 이게 이해가 안되네
I have the same question😐
It should be D (- infinity,4) U (4, infinity)
I had same problem
2 weeks of learning done in 30 minutes, sweet.
truly wonderful, i can imagine how much effort it take to make these videos .
thank you :)
Your explanation was great and helped me significantly. Thank you.
My 8th grade algebra teacher was teaching this and I have mid terms coming up so I had to review this topic because it confused me so much, so far this is helping a bunch.
yo what I know now you are at your 9th grade but how come you studying this at year 8, anyway gg
bruh your school's lesson is so adv, where's that??
Really helpful and figured out exactly what I needed to know, thanks!
Your video really helped me get through this lesson. I believe it had something to do with the way that you broke up the solution process. Thank you so much.
Thank you. This is going to help me so much for my math college courses. Thanks a bunch.
Studying for my high school math cert. You are a lifesaver.❤❤
At 23:10 shouldn't the domain be (-infinity,4)union(4,infinity)instead of -4?
i think so
should be +4
i was bout to comment that...
It should be +4
yeah I stopped at 23:10 to read comments. I knew someone intelligent would comment :)
How about this if I say
Domain =(-infinity,-1)u[-1,4)u(4,infinitey)
Is that right or wrong?
the domain for the last example is from negative infinity to 4 and from 4 to positive infinity. you said it was up to -4 which is wrong
Glad you learned!
taking calc over the summer so trying to get a head start thank you for your videos :D
you are such a g i think imma pass my exam bc of you!!
23:10 hmm should be +4 not -4
Oh thnak you thought i was wrong
Yes
Yooo, I was thinking the same thing
why can't I understand this WTF
Same. 😔🤜🤛
omg Kageyama LMAODKD but SAME OML
Well I'm dead
Yo bro this is hard asf my nigga
Learn functions, finding domain and range, graphing functions first
All your tutorial videos have helped me a lot. May the good lord bless your work.🙏💯
you are a life saver...
You make my professor look bad, I’m actually learning and I haven’t recalled a moment in life where I actually learned since I took geometry in my sophomore year of highschool so thank you
When I learned about Limits last week on college, I went full Cady Heron in my mind =]
Always appreciate a mean girls reference 😌
u study this in college???
@@krkmjr8429 it was university to be exact.
@@krkmjr8429 you have to know how to graph piecewise functions to evaluate limits in college
@@nandolance91 yea im learning graph rn on high school
its 2022 and your videos are still useful
@23:52 WHY IS -3 included and not excluded?
At 23:50 isn't the "-3" supposed to be in parentheses() rather than brackets [ ] because technically it doesn't include -3...??
Yes exactly
If you look at the graphI -3 is still included because the domain goes to the left continuously
Gabe Baste But it’s in regards to range not domain, therefore shouldn’t it exclude the -3?
OMG THIS VIDEO HAS EVERYTHING I NEEDED. THANK GOD I WILL PASS MY CALCULUS 1
calculus 1 I’m learning this in algebra 😭😭
@@btslover2.048 same alg 2
Thank you so much! This helped immensely :)
Can I hire your brain for like every second that Im alive?
At 21:31 why did you plug in 6 if you can do 5? please enlighten me, thanks in advance :)
big respect
My question refers to the 2nd problem. Now im fully aware that you can't have a negative under a radical but hypothethically speaking what it you had a function of -x under a radical for x less than 0, how would you solve that?
It isn't possible unless you use complex numbers
MR. Organic Chemistry Tutor, thank you for another off the mathematical charts video on Graphing Piecewise Functions, Finding Domain ,Range ,Limits, Continuity and Absolute Value. There is a possible error on the range where you have [-3,-3], please check video.
23:00 domain would be from negative infinity to 4 union 4 to +inifinity right; not negative 4?
Is it true that if you take MJ it would be easier for you to memorize readings? dos it also apply to mathematical formulas?
At 23:00 there is a mistake. We're only human. Could you put something in the video description to correct that? Thanks.
champ you are the best
Wooa! I just hit on it now!
Do not bother. I just thought better of it. For the first case, y = - 3; so, it is not dependant on x. Hence, we are safe to say the range of values starts from - 3 since y is - 3.
21:31 why did he plug in the 6 was just random or did he have something else done before hand. thank you in advance
Do you have video about piecewise function for wind direction with angle please
ok , I like this solution in this video .
THANKS ALOT BOSS!
Can someone explain 4:01 ? Why did he start with y intercept? Why doesnt both ends go infinite and only one has the arrow?
I'm a little confused...Shouldn't the first problem's range include the discontinuity on the y-axis?
sir u r great
Thanks!
if 1/x only allows negative numbers according to its instructions how is it its range includes negative infinity?
What is the value of f(x) if the corresponding y-value is neither a hole nor a solid hole but just a line. Do you read off the graph ?
I would say you would have a horizontal asymptote giving a domain of (-infinity, infinity) and the Range is [1], the limit as x approaches -infinity is -infinity, and as x approaches +infinity is infinity.
The organic chemistry tutor saved my life🥲
thanks
The guy is dangerous
isnt the domain suppose to exclude 4 not negative 4??
yeah i was wondering the same this
For the range of the last question, shouldn't it be :
R(-3, - 3) U [0, 3) U (3, infinity)?
Pls, respond to this; so I can get it clarified. Thank you very much!
Love from 🇳🇬.
thanks julio
If doesn't have any equal sign means open circle?pls enlighten me
At(- infinity,4)U(4,+infinity)
For the last one, the range should be [-3,0] U [0,3) U (3,infinity)
there's nothing there between -3 and 0
question, can't I directly answer [-3,3)U(3,+∞)?
shouldn't the x asix of radical function start from 4 because we cant take 1 as it is stated in question x>1 ( not equal to 1 )
In 23:02 why did you take negative 4 in the interval of domain?
Can somebody please clear this doubt?
I guess that was a mistake, also I guess the range should be from [-3,3) union (3,+infinity) not [-3 to -3).
how do you know when to put an open or closed circle when graphing?
let's say if x is equal to or greater than 2, a closed circle should be used. If x is simply greater than or less than 2 but not equal to 2, then an open circle should be used.
oh ok thanks man
4 years :(
Is it even possible to find the range of such piecewise functions without plotting graphs?
hello, how did he find f(4)=6 in the end?
i am confused with the use of ( ) and [ ] or [ )
You use "(" when the inequality uses less/greater than, while you
use "[" when the inequality uses less/greater than OR EQUAL TO.
Examples:
x < 2 = D(-∞, 2)
x ≥ 3 = D[3, ∞)
3 < x ≤ 8 = D(3, 8]
2 ≤ x ≤ 6 = D[2, 6]
At 24 minutes you said that it doesn’t include -4 but I think you meant it doesn’t include positive 4
oh god,thatswhy this topic was so tuff,i never attempted this part in exam.and still mind become mouf.
tnx bro
tysm
Why do we need those red statements?
why was x-1 equal to 0 became 1/4 x?
fr he should say every step so we can learn
At 21:18 why would you plug in four when it not x is greater than or equal to four it just x is greater than four, wouldn't that mean that four is not included in domain, why not use five?
I just realized that four is included, I was only thinking of 2x-5 as an individual function, 4 is included because of the second rule in the piece wise function my bad.
same question
The domain for the last piecewise function should be 4 instead of -4.
Yes
o chem broski I love you
In domain +4 is not included not -4 ,,point of correction
Are you an AI?!
Cos you're so cool.❤
F of 4 is equal to 6...is this correct?
No, it should have been 3. Using either the absolute value equation or the linear equation you get 3.
@@lanaichild926 im confused because of this as well, how did he get 6??
basic high school level !
why is the domain -4 in the last question
its an error. I hate it when he does it and not correct it.
22:51 sec the domain will be R - {4} not -4
hi.. can i ask one question?
iam talking about question 2
Hanani tngok ni , aku kt comment
Ya sayaaaaaaaa
Abg kt video tu beleter ape , tam pamham amkum
as you can tell id rather be around loved ones and not associate with people i have no clue about. It was a mistake, a massive one to be frank
different values and different aqpproach to business and frankly life. this is the end to whomever is inside my business
y do u feel entitled to me? ask yourselves that.
ik watever i say doesnt matter cuz im a 2d caricature and have been for a long time to many of u
In last example the domain is wrong. It is 4 not negative 4
good video but just not as long tho👍
Can someone tell me where did he got 6 from at 21:33 I am so confused :(
you can use any number, as long as it's greater than 4, hence the x > 4.
@@CriVal4 so if it any number greater than 4, will it still be an open circle or will it be closed??
@@August00098 hmm, it's been so long I have forgotten T-T, but my assumption is put open circle only if you've reached the limit given on the condition, on the video it was 4 and -1
can I ask for help?
Jesus Christ died for our sins so the devil would not drag us to hell. Jesus tells us to profess with our tongue and believe in our hearts that He is Lord so we can make it to heaven; however, many of us have rejected Him and chose sin. pls come to Christ and reject the true evil: the devil. as long as you believe and walk in His ways, you will reach the Divine Kingdom. God bless you all🥰💞
a god can die? if he died how is he helping? why do you worship someone cant forgive you unless he dies although he is a god? but he is the son of god too? whos god then?
N O
@@krkmjr8429you do not seem to understand Christianity
explain then URmajesty
@@krkmjr8429 oop sorry lol i never saw this. Jesus is God but in the flesh. in the old testament (OT), they sacrificed goats that had no blemishes in order to atone for sins. the only way for sins to be atoned for is for something completely blameless to take on the sins for all. no one that has walked this earth was completely blameless, so Jesus came to do that for us
Before to solve the question plz sir define the topic first.
Naimatullah Khan it is truth he has other videos on this mate...
@@DragonKidPlaysMC send a link plz
I can do the math is anybody else getting confused on the graphing part
How come he uses y intercept and then sometimes says fuck it
22:50
I just came to know that his name is Julio Gonzalez
i still dont get domain and range its so confusing
te amo
Isn’t 3 not included
Number one thing is these videos don't explain how they get the answer they just know so they write it on the graph but never explain how they got it
x --> + infintity, means x aproaches infinity from the right !!!!! not from the left !!! this is completely wrong
What? no. It means x is approaching positive infinite.
bahahahah, no. how could a value approach positive infinity from the right? that would mean X is greater than infinity, i.e. not possible. Think about that for a second...
X approach + infinity means it approach from the left, and x approach - infinity means it approach from the right.
THE LIMIT DOES NOT EXIST!
