1. 5.3: Function Rules, Tables, and Graphs

2. Modeling Functions There are three ways to model a function:
Rule (equation)
Tables
Graphs
 shows how variables are related
 identify specific input and output values
 gives a visual picture
Remember:
Domain: Independent variable (inputs)
Range: Dependent variable (outputs)
 graph on horizontal axis
 graph on vertical axis

3. Modeling Functions
Ex1) Model the function rule using a table of values and a graph.

4. Modeling Functions
Ex3) Model the function rule using a table of values and a graph.

5. Modeling Functions
Ex4) Model the function rule using a table of values and a graph.

6. Modeling Functions
Ex2) At the local video store you can rent video games for $3 each. It costs you $15 up front for the video game membership.
Define the two variables in this situation and write a function rule to represent your total cost. Use function notation
Make a table of values and a graph using the function rule.
How much would your total cost be if you rented 13 video games in a month?
