Answer 1

Domain is the set of x values, or the inputs.

Range is the set of y values, or the outputs.

They are unique.

Looking at the table,

the number of hours is the input on which we have the cost, the output.

So,

We get domain from number of hours

We get range from total cost

1, 3.5, 5, 7.5, and 9 ---- hours (domain)

B is right.

Now,

Range would be the total costs, which are:

2, 6.5, 7, 9, 12.5

F is right.

Correct answers are B and F
