- čas přidán 10. 09. 2024
- This algebra 2 math video tutorial provides an introduction into function notation. It discusses evaluating functions with a single variable x and using 2 variables x and y. It explains how to find the missing x or y variable using techniques such as factoring trinomials, GCF, and by grouping in addition to using the quadratic formula. This video contains plenty of examples and practice problems.

The braincells that I lost in 9th grade Algebra are being regained. Thanks a lot.
the brain cells i lost are still lost and this video made it a whole lot more worse
@@diamondrichards9270 but it's really simple even a 5th grade person would understand.
@@DaMightyfire i used to love these type of math problem when i was 7 years old
@@sanopann1896 same
@@DaMightyfire Then i wonder what brings you here now?
i tried learning pre-cal in advance so that I wouldn’t suck in class but i never really got anything right and watching ur video helped a lot 🙏🏻

never understood math within 1 minute and 4 seconds that was so easy to understand THANK YOU.
Never would have guessed that it really is this simple.
@iamafraidofwomenI think he's good
Fr
Thank you so much for these! I’m self teaching myself honors pre calculus this year and you’re making it a lot easier!!
the first two was easy😭😭😭 im really confused at the 3rd and 4th one
this guy cover everything in the world. I love u man
This man is out here saving lives , and he thought we wouldn't notice
This guy is a child of god, who needs math teachers if this guy makes it understandable in two seconds.
MR. Organic Chemistry Tutor, thank you for a Basic Introduction of Evaluating Functions using real numbers.
Your a lifesaver for all college student,hope we see your face soon
Ur doing this in college? My child is doing this in 7th grade!!
This man is an absolute legend.
DUDE, YOUR A LIFE SAVER 🙏
@iamafraidofwomenoh definitely 😂
It would be fun if online teachers teaches this way
Greatvideos dude. Thanks.
This one.is a lil too advanced for.me.at the moment. Will be back to this one.soon.
in which standard/rank/class are u in lil bro??
You explanation makes the whole subject way more easier! Thank you so much🙏
teachers usually teach you questions 1-3 and then give you exams like question 4
hello teacher , in exercise n 4 i tried to solve it using the formula ( -b +/- root of b^2 - 4ac ) / 2a but i my soluition was different ? is there a mistake in using this formula in this example?
Great explanatory video. Thank you.
Why did we subtract -100 from 48 and not the 5y^2
You didn't use MDAS rule? Because you said in problem "9+15-7" is 15-7 first?
you get the same answer either way lol
Best tutor ever
what is the purpose of subtracting 5 to x^2 - 4 +9 and how did that happen? it is in 3:53 minutes of the video. Thanks
Right. I didnt really understand when it was said that they " factored the trinunerial of the quadratic formula" 3:52 I dont understand how x= 2 the checking yes but how is it equivalent like how is the 4 = -4x but
the only way to help this guy back is to watch the ads that popping out on his video
Thanks again dude
I’ve noticed something when solving a Quadratic Formula by factorisation question.
If the co-efficient of A is 1, then the two numbers multiplied to make the product will have to change into its inverse
Example
x^2 - 4x + 4
Because the co-efficient is one, I could find the product of 4 but it needs to total to -4. This will be -2 and -2
All I have to do is the inverse of -2 which would be 2. The answer is x = 2
Does this apply for every quadratic formula problem with the co-efficient of A being 1??
So you were saying that X always equals the inverse of the two middle terms
Great video! You sound like Mark Wahlberg btw!!
This channel made me understand the lesson than my math teacher.
He talk and move too fast that I can't follow.
Is this a real person ? Doing all the videos thumps up greetings from Egypt
Here i am studying because tommorow will have a test
Wish me luck!! 🙏🙏
Bro your voice is so pretty!!!
for problem at 10:00 the answer shouldnt it be 5.2
nope, you can test the function by replacing X with 4 and Y with the result, and if you set Y= -2 the function will turn out = 48 + 32 +20 which is 100, and the problem confirms that f(x, y) is equal to 100.
Thanks you alot bro really appreciate it bro
What about BODMAS rule?
Do you need to apply GEMDAS?
I forgot all math, I don't understand questions 3 and 4 😅😭
I did not understand what was happening in problem number four at all😅😅😅
i didnt either at first, but after watching his vid on polynomials it make a little more sense
9:42 quadratic formula for finding y
I am lost in question 4
Same
Note to self: x represents the x on the other side of the equation, and f represents everything else. Makes a lot more sense.
How did you get 5x50 and 5x2 in 6:44
thankyou!
can someone explain huhu, how it -260 become -26 and 10 and 26 -10 huhu ? 7:10
The "26 - 10" is just an option but the answer is "(-26) 10" if you multiply those two you will get 260 and for (-26) 10 if you add them up you'll have the sum ( -16y)
Interestinggg
this is so confusing how am i supposed to do physics and chem if i cant get the basic math. im dying and literally crying here..... UGHHHHHHHHH
it wont click for the first time
just keep trying
@@marouans7755 I had this lesson for 5 years and still wont click >
I don't think it's proper to call f(x) as f.
woah! 999 likes. If you're seeing my comment and watching this vid, you're a legend.

🔥🔥🔥🔥💯💫
completely lost me on question 3. tf is going on 💀
i watched some videos on polynomials and now im a little bit less lost :-)
thank u but please speak louder i cannot focus 😭

How can a valid second degree trinomial function have no real solution? the discriminate is -5
Am lost at ques 3
You have to learn Quadratic Equations first
Sorry I'm bobo talaga sa math
sameee, lalo na sa question 4 omg
