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?

The amount you earn by working x hours per week is,
                             y = 8x
Given that you work 40 hours per week, the domain should be 40 or less or 0 to 40. The range is determine by multiplying 0 and 40 to 8 and the answer would be,
                                y  = 0 to 320

You would have to multiply all of the numbers

If you make it a little more clear i can answer it
