Unit 02
Absolute Value Functions, Equations, and Inequalities
This unit takes a close look at the absolute value function: what its graph looks like and what makes it special, how stretching, compressing, reflecting, and shifting the graph changes it, and how to set up and solve equations and inequalities that involve absolute value.
