# Lesson Plan: Solving Absolute Value Problems Mathematics

This lesson plan includes the objectives and prerequisites of the lesson teaching students how to solve equations involving absolute values algebraically and graphically.

#### Objectives

Students will be able to

• solve absolute value problems that involve combining transformations, reflecting graphs in the - and , and finding the domain and range,
• state why the inverse of a linear absolute value function does not exist,
• sketch graphs of transformed linear absolute value functions and use them to solve equations and inequalities.

#### Prerequisites

Students should already be familiar with

• absolute value linear equations,
• absolute value linear inequalities,
• reflecting graphs using the absolute value,
• combinations of transformations of functions,
• domain and range of functions,
• the inverse of functions.
