Question

The cost, y, of taking a rideshare per hour, x, is shown in the table.

Cost of Rideshare per Hour
time (hours) 8 9 10 11 12
cost ($)
22.24 25.02 27.80 30.58 33.36
What type of function could be used to model the cost, y, of a rideshare as a function of time, x?

(1 point)

exponential decay function

quadratic function

linear function

exponential growth function

Answer 1

Linear function.

The cost increases by a constant $2.78$ dollars each extra hour (25.02−22.24 = 27.80−25.02 = 2.78), so the relationship is linear.
