Outcomes
In this lesson you will learn
- a review of the absolute-value function
- the concept of a piecewise function
By the end of this section students will be able to:
- model problem situations with combinations and compositions of functions
- analyze relations, functions, and their graphs
- use tables and graphs as tools to interpret expressions
- investigate and interpret combinations and compositions of functions
- analyze and solve polynomial, rational, irrational, absolute value, and trigonometric equations
- analyze and solve polynomial, rational, irrational, and absolute value inequalities
Introduction
In this section you will, first of all, review the absolute-value of linear functions. You will then extend your understanding by applying absolute-value to non-linear functions. Equations and inequalities involving absolute-value will also be solved.
This section of study requires about 3 hours for completion.

To be successful in this lesson, it would be helpful to know the following:
- how to graph linear absolute-value functions
- absolute-value of a real number
- slopes of tangents
- domain
- definition of the derivative
- right and left hand limits
