How to Find Critical Points with Derivatives | Calculus 1 Exercises

We go over how to find critical points and critical numbers of a function using the derivative. In each problem we take the derivative of the function and determine where the derivative doesn't exist and where the derivative is equal to 0, these x coordinates are the critical numbers. We then plug these critical numbers into the original function to find the y coordinates so we can write the critical points. #calculus #apcalculus
