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
