Is the total cost (output) a function of the number of tickets purchased (intput)?

• Yes, it is a function because each input has exactly one output.

• No, it is not because each input has more than one output.

The mapping diagram matches one input to exactly one output. It is __________________.

• a function

• not a function

• scatter plot

Identify the function rule for "The output is 6 times the input."

• x = 6y

• y = 6 + x

• y = 6x

• y = 6 - x
