You helped me as much as I can not write because I am hindi medium student not able to understand english much but you gave subtitles so ❤❤❤❤❤❤❤❤❤❤❤❤❤💞💓👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
+joshua kusuma yes. I'm sure I have at least one video on my channel of a function with more than one inflection point, if you wanted to see an example.

Great video, I learned from another video the concavity and came for the inflection point, but I reinforced my understanding of concavity while watching your video. 2 birds on one shot :) thanks!
Hi great video, but one question: I understand here you are told there is a point of inflection so you can use f''(x) =0 to find this point. But if you just had that equation and were asked to prove it was in fact a point of inflection at x=2, how would you go about it? I'm aware that a point of inflection implies that f"(x)=0 but I also know that f"(x)=0 does not imply that it is necessarily a point of inflection.
Thanks. You'd do literally exactly the same thing. Although we knew ahead of time in this case that there was a point of inflection, we didn't know where or what it was and when we looked for it we didn't use the fact that we knew it exists. If you're just told to investigate then you do all of the same steps. The only difference is it's possible to conclude that there are no inflection points.
Sorry, missed the notification on this one somehow. I don't think so. I don't see how using the third derivative can be helpful when looking for points of inflection. For points of inflection you want to know where the second derivative is positive, negative, and zero. The third derivative basically only tells you when the second derivative is increasing, decreasing, or constant.
Critical numbers are values of x where f'(x) = 0 or where f'(x) is undefined, but f(x) in this video is a polynomial and polynomials are never undefined.
This helped me more in 12 minutes, than my professor could in an hour and 15 minutes, Thank you!
LOL
I love worthless professors (: my favorite
took my professor 3 hours and this helped more.

@Isaac Armani instablaster :)
short, simple and to the point, precisely what's needed 👏
i rarely comment on videos, but I just need to tell you how great you are, thank you so much!
Thank you very much! This is much more helpful than other videos I've watched or examples I've looked at.
I was slightly confused in my class, but this video helped clear it up. Thanks!
You saved me, may god reward you the best in your life
This video lecture really helped me 100 times in a couple hours than my lecturer who took more than 3 hours teaching me
Big up
I'm very impressed, I'm sure i will do great in my exams .All thanks to you.
One of the most useful content in youtube
Very easy to understand. You made this feel like it was some basic algebra problem!
Your teaching procedure is so good. You clear my all points thank u soo much Sir!
Thank you, thank you, thank you! You saved the day! :)
you rock man. Spent a week at outdoor ed as a cabin leader and came back with a test as a welcome back gift. this helped
hope your test went well 5yrs ago

Thank youu!!!
thank you soooooooooooooo much
Thanks for the vid! Also, you sound like Yuri Lowenthal. :o
Thanks alot sir 🙏🙏🙏
thanks so much
I want concavity for the points X= -1/2 ??
Thank you ^_^
Very clear
thnx a lot please
nice vid man
Excellent
Thank you brah
Thank you sir
excellent sir
Is it possible to have two different x values which would lead to two different points of inflection?
+joshua kusuma yes. I'm sure I have at least one video on my channel of a function with more than one inflection point, if you wanted to see an example.
the f''(x) would have to be a quadratic
That was very helpful, thanks man.
r u somali? just wondering ,

Oh ok, I understand it now thanks! Also is it worth using f'''(x) instead of doing this method for a point of inflection?

For points of inflection you want to know where the second derivative is positive, negative, and zero.

i think its good that you are doing question but make it more clear
Thanks, does ciritical number is only for f'(x)=0?
Critical numbers are values of x where f'(x) = 0 or where f'(x) is undefined, but f(x) in this video is a polynomial and polynomials are never undefined.
