The cost of riding in a taxi, y, for x miles can be modeled using a linear function. The taxi driver charges a fixed cost of $5 plus an additional cost of $2 per mile. The driver will only drive a maximum of 60 miles per trip.

For one trip, what is the range of the function for this situation?

Which of the following relations defines a function?

• Each student’s age, x, and the student’s number of siblings, y.

• The number of days in the month, x, and the number of days it rains during the month, y.

• The time spent traveling, x, and the distance traveled, y if you drive at a constant rate of  60 mph. 

• The temperature outside, x, and the number of ice cream cones sold, y.
