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
