Also it's cool how you just get straight into working. Most people try to explain the abstract idea before any examples and that seems utterly backwards to me.
Just subbed and turned on notifications for your channel! Thanks for being such a great instructor! Where did you complete your college education and in what field?
Aw thanks! I'm glad you're liking the videos. :) I studied at the University of Notre Dame. I actually majored in Psychology, but tutored calculus during my time there.
Why not check the next derivative and see if it's increasing or decreasing at the inflection point? f'''(-1) = 12 which means f''(x) is increasing at the inflection point, so the function f(x) goes from concave down to concave up.

Your voice is so calming, it balances out the mildly panicky voice in my head
You'd be great at guided meditation, relaxation, ASMR, etc; one of the most placid voice I've heard.
you're a life saver, thank you so much for these videos, they are so simple and straight to the point. ❤️❤️
Thank you so much, I highly appreciate this video. spot on.
Thanks! :)
Most concise video & explanation on YT.
Aw thanks! Glad you liked it.
such a nice teacher, thanks!
Very well explained! I understood 100%!
+Jeffrey Chue That's awesome, I'm so glad it made sense!
THANK YOU!!!!! You saved me I was having a breakdown because my textbook made no sense
You're welcome, I'm so glad this helped!!
Mam, the way u explains was just awesome
you're really good at explaining ... also thanks for those helpful lessons
+7amad Mohammed AlDhanhani Thanks! Glad you like them.
+CalculusExpert.com ( could you please in the very soon future make & post integration or untiderivatives cuz we will be studing them )
Thanks again
You're an amazing teacher, thank you
Thank you so much, I'm happy to help! :)
I like ur lectures

Miss have you made any video covering the topic derivatives of higher degrees .It will be very helpful if you send me a link!
Thank you! This video was very helpful :D
+Olivia Figueras Awesome! I'm so glad it helped!!
i understood all of it.. i have exam tomo nd i was so worried bout it thank u sooo much 💕
Oh good! I'm so glad it helped, and I hope your exam went great! :D
thanks help so muj..
what to do if we have a rational inflection point value?
New sub! So glad I found this vid
Thanks for subbing, Kristi!
Thank you so much!
You're welcome! :)
that was amazing
F"(x) =+ means local min and if - then local maximun there
thanks!
You're welcome Deven! :)
FROM MOROCCO THANK YOU

plz solve trigomometry inequality by this method
CD means convex
Mistake at f(-1)...mam... I think the answer is -2, instead of 10.
Why do you say that? I still think f(-1)=10.
f(-1) = 2(-1)^3 + 6(-1)^2 - 5(-1) + 1 = -2 + 6 + 5 + 1 = 10
HALLELUJAH
concave up = cup, concave down = frown
concave up.... smiling
concave down.... frowning.
Why is that the other tutor ....takes the 0 into the right side like this 12×+12=0
tyyyy
You're welcome, Momtaz!! :)
