Outcomes

In this lesson you will learn

  • to solve polynomial inequalities by using sign graphs (number lines)

By the end of this section students will be able to:

  • analyze relations, functions and their graphs
  • use tables and graphs as tools to interpret expressions
  • analyze and solve polynomial, rational, irrational, absolute value and trigonometric equations
  • analyze and solve polynomial, rational, irrational and absolute inequalities
  • model real-world phenomena with a variety of functions/relations
  • determine the equations of polynomial and rational functions
  • factor polynomial equations

Prerequisites

To be successful in this lesson, it would be helpful to know the following:

  • formula for volume of a rectangular box
  • how to use a sign graph (number line) to solve quadratic inequalities
  • how to find roots of polynomial equations
  • interval notation
  • formula for volume of a cylinder (for # 51)
