An air conditioner repair service charges $60 for a service call plus $30 per hour for labor, from 1 to 6 hours. The total

amount charged to the customer m, for any number of service hours, h can be represented by the function

Answer:

[90, 240]

Explanation:

Here, the range can be found by considering the values of m at the extremes of the domain.

for 1 hour, m = 30(1) +60 = 90

for 6 hours, m = 30(6) +60 = 240

The range of m is [90, 240].
