Lesson Summary:

In this lesson, constant and absolute value functions are explained and graphed with examples given. The differences between the two types of functions are highlighted, with constant functions having a set value that is always the same, and absolute value functions having a vertex or turning point that changes the value of the function based on whether the input is negative or positive. The lesson breaks down how to graph both types of functions using a simple chart and examples.
