1. for each graph:
• list the y-coordinate terms as a sequence
• identify the first term.
• describe what happens to the y-coordinates as the x-values increase by 1 (common difference)

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
