Question 1005082: Ronnie is considering switching cell phone plans. The new plan would cost $5.95 per month plus $0.04 cents per minute.
a. What are the restrictions on the domain and range of this situation?

Let the total cost for x minutes be C.
The domain must be x >= 0, since you can't make negative calls. The range must be >= $5.95, since even if zero calls are made, you still owe $5.95.
The function would be
C = .04x + 5.95
