Outcomes
In this lesson you will learn
- to solve absolute-value inequalities
- to write inequalities to interpret number-line solutions
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
Prerequisites
To be successful in this lesson, it would be helpful to know the following:
- how to solve inequalities
- the effect multiplying an inequality by a negative number has on the inequality sign
- interval notation
