# 1-2/1-3 Characteristics of Functions; Pre-Calculus

Understanding the definition of a function is the basis for this section. We will investigate further the characteristics of different functions as well as how they are similar and different. This unit you will learn

- How to determine if a graph is a function or not
- How to determine end behavior of a function
- How to determine if a function is even or odd(algebraically and geometrically)
- How to determine the intervals that a graph is increasing, decreasing or constant
- How to determine the vertical and horizontal asymptotes of a function

So without further explanation lets get started

## How to determine if a graph is a function or not
