Learn how to find relative extrema and justify using first derivative test

The video tutorial covers identifying relative maxima and minima of a polynomial function. It begins by discussing the continuity of the function and finding critical values through derivatives. The first derivative test is used to determine whether these critical points are maxima or minima by analyzing slope changes. The tutorial explains how to justify these findings and identifies intervals where the function is increasing or decreasing.
