Questions

Mark's car's gas tank can hold 14 gallons of gas. It gets 30 miles per gallon of gas. Let the relationship between the distance that Mark can drive and how full his gas tank is be a function. Define the inputs and outputs, and find the range of this function.

Answers

The inputs would be the number of gallons of gas in Mark's tank. The outputs would be the number of miles Mark can drive. The range of this function would be all of the numbers between the minimum number of miles that Mark can drive and the maximum number of miles he can drive. The gas tank can hold anywhere from 0 to 14 gallons of gas.
