If you work for an hourly wage, your gross pay is a function of the number of hours that you work. your hourly wage is $8 per hour. assuming you work 40 hours per week, what is the practical domain and the practical range of the function? a. the practical domain is 0 through 8. the practical range is 0 through 32. b. the practical domain is 0 through 320. the practical range is 0 through 40. c. the practical domain is 0 through 40. the practical range is 0 through 320. d. the practical domain is 0 through 32. the practical range is 0 through 8.

The correct option is C.

Step-by-step explanation:

It is given that gross pay is a function of the number of hours that you work.

Let y represents the gross pay and x represents the number of hours. So, the value of x and y can be negative.

Hourly wage = $8 per hour.

The weekly gross pay function is

             .... (1)

Domain is the set of inputs and ranges is the set of outputs.

It is given that you work 40 hours per week. It means the value of x lies between 0 to 40.

Domain = [0,8]

Substitute x=40 in equation (1), to find the gross pay when number of hours is 40.

Range = [0,320]

The practical domain is 0 through 40. The practical range is 0 through 320.

Therefore the correct option is C.
