How to determine the max or min of a quadratic function in vertex form

The video tutorial explains how to rewrite functions to understand transformations, focusing on identifying the vertex in equations. It highlights the importance of recognizing the vertex as H, K and discusses how to determine if a graph has a maximum or minimum based on its direction and reflection about the X-axis.
