Absolute Maximum and Minimum Values of a Function - Calculus I

This video teaches students how to use the closed interval test to find absolute maximum and minimum values of a function. In particular, I use the first derivative to find critical values of the function. From this step, I show how to find the absolute maximum and minimum values within a closed interval.

Very concise and gets straight to the point, unlike most tutorials which ramble around the theory too long and starts with too easy problems before getting to one that you'd generally see on the exam. Subscribed!

hello!! i am stuff with this one. pls help me out.
for all real values for x, what will be the minimum and maximum value of-
(x^2-3x+4) / (x^2+3x+4)

[cstrombone]

How did I read your channel name as Worcestershire sauce the first time? How. How did I do that?

[rishabhyadav]

easily comprehensible videos. But sir you should first solve the question already on board and then teach. This will save yours as well as other students' time.

[everybodylovestaco]

why did u put f(-2) when x=2?(one of the critical points)

[Evelyn]

would the two middle numbers become the local max and min?

[reenarai]

thanks sir
Sir plzz plzz solve this question also : f(x)=|x+2|-1
