I need help with a math question

Question

Can you someone here help me with this math question with both the answer and work involved?

"Consider a function that describes pay and the number of hours worked in a weekly pay period. An appropriate range for this function could be:
A) $0 to $600
B) $0 to $50
C) 0 to 600 hours
D) 0 to 50 hours

Answer 1

Confusing question.  I think they want you to know that the independent variable, x, would be hours and the dependent variable, y, would be pay ($).  Range refers to the smallest to largest values of the dependent variable, so it would be A) or B) cause those are in the correct units, $.  Both have a starting value of $0 that would be your pay if you worked no hours (x=0 hours).  I'm guessing the answer is A) $0 to $600 because $600 seems a more appropriate upper bound for a week's pay than $50.

 

The Domain refers to the smallest to largest defined values for the independent variable, x, in this case hours.  So C) and D) would refer to the domain.  Both start at 0 hours which is appropriate.  There are only 168 hours in a week though, so 600 hours is too high.  So D) would be appropriate for the Domain.

Answer 2

Hi Ryan,

 

Is the function describing the amount of pay based on the number of hours worked in a weekly pay period? If so, the answer would be choice A. If the domain were asked, the answer would be choice D.
