2. Functions Chapter 4
I can determine if a function is linear or nonlinear based on its characteristics.

3. If it crosses the graph more than once it is ______ a function! once
Vertical Line Test
Given any vertical line, if it crosses the graph _______ it is a function.
If it crosses the graph more than once it is ______ a function!
once
NOT
Function
Not a Function

4. Functions can be linear or nonlinear
Functions are nonlinear when they don’t have a constant rate of change.
Functions are linear when they have a constant rate of change (slope).

5. Function YES NO Vertical line test Nonlinear Function
Does this graph represent a function?
If it is a function, decide if it is linear or nonlinear.
Explain your reasoning.
Function YES NO
Vertical line test
Nonlinear Function
because it is not a
straight line.
