Question

Kashawn works at a pizzeria for $10.00 an hour and he can work a maximum of 10 hours a day. If represents the number of hours Kashawn works while () represents his pay each day, which of the following best represents the domain?

Answer 1

He wins $10.00 per hour.

He can work a maximum of 10 hours per day.

x is the number of hours that he works, and f(x) is his daily pay.

f(n) = $10.00*n

First, let's find the domain:

We know that, at a maximum, he can work 10 hours per day.

The set of possible values of x, the domain, is:

D: 0 ≤ x ≤ 10

From this, we can also find the range, because f(x) is a linear function with a positive slope, the minimum in the domain will map in the minimum in the range, and the same for the maxima.

Then the range will be:

R: f(0) ≤ f(x) ≤ f(10)

$10*0 ≤ f(x) ≤ $10*10

$0 ≤ f(x) ≤ $100.
