Piecewise functions

Question

The rates for a parking garage are $3 per half hour and $8 maximum for 12 hours. Write a piecewise function for the rates at the parking garage.

Answer 1

f(x) is the rates for parking garage, x is the numbers of half hour

 

f(x) = { 3 x   (1 ≤x < 24)

         { 8       (x = 24)
