Bellwork 1) How do you know if something represents a function or not?
2) Is the table a function? Days (d) Cost (c) 1 $14 2 $20 3 $25
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.

Make sure you label whether it is linear or nonlinear
EXIT TICKET Create your own Function representations. One must be a sketch of a graph, and the other can be a set of ordered pairs, a mapping or a table Make sure you label whether it is linear or nonlinear
