Graphing Absolute Value Functions

The video tutorial covers the topic of graphing absolute value functions, focusing on plotting points, identifying the vertex, and understanding the domain and range. It includes examples and exercises to help students grasp the concept of graphing these functions, with a particular emphasis on the characteristics of the graph, such as the V-shape and the vertex as the highest or lowest point. The tutorial also touches on the effects of manipulating the function and provides guidance on completing exercises independently.
