We will explore How to find critical numbers of a function can help students understand and learn algebra.

To find the critical values of a function, we must set the derivate equal to 0. First, we find the derivative of the function to be We can then factor out a 6x and set the expression equal to 0

Steps for finding the critical points of a given function f (x): 1.) Take derivative of f (x) to get f ‘ (x) 2.) Find x values where f ‘ (x) = 0 and/or where f ‘ (x) is undefined 3.) Plug the values obtained
