Introduction
Functions
A function is a set of ordered pairs for which each x value is paired with only one y value.
After compleing this activity you should be able to determine if a relation is a function and compare two functions.
Process
What are some real world examples of functions? What is a one-to-one function?

Can you determine if the tables, graphs and ordered pairs are functions?

Can you compare two functions using a table and graph?
Evaluation
You have to submit the following product based on what you have learned from the previous page.
1. Create a real world scenario that uses function properties (using the video that compared the gumball machine and the parking garage.). Your answer should include a written explanation of your example, a mapping diagram, table of values, and a graph for each one..
2. To compare functions use the following scenario. (You will receive information graphing the costs for Wally's Water World and a table showing the cost for Tonly's Tidal Takeover.)
Wally's Water World is a water park that is very popular with teens.
A new water park, Tony’s Tidal Takeover, just opened. You have not heard anything specific about how much it costs to go to this park, but some of your friends have told you what they spent.
Each park charges a different admission fee and a different fee per ride, but the cost of each ride remains the same within the given park.
If you only have $14 to spend, which park would you attend (assume the rides are the same quality)? Explain.
