# INTRODUCTION OF PARENT FUNCTIONS

### THE BASIC FUNCTIONS THAT WE WILL INVESTIGATE IN ALGEBRA 2

## Three of the basic functions we will learn about in Algebra II

- Linear
- Quadratic
- Cubic

## LinearDomain - X is all real #'s Range - Y is all real #'s | ## QuadraticDomain - X is all real #'s Range - Y > 0 | ## CubicDomain - X is all real #'s Range - Y is all real #'s |

Compare each function with it's graph and doamians and ranges respectively.

How do each vary?

How are they the same?
