Question

Barb is paid $8 an hour at her new job. She wishes to graph her total pay, T, as a function of the number of hours, h. Barb works between 5 and 25 hours a week.

Select from the drop-down menus to correctly complete each statement.

"To best show this information, the scale for the T-axis of her graph should go from 0 to at least (5 , 8 , 25 , 40 , or 200). The h-axis if her graph should go from 0 to (5 , 10 , 25 , 40 , 200)

Answer 1

T is 0 to 200 H is 0 to 25 

Answer 2

Let

T-----> the total pay

h----> the number of hours

we know that

`T\geq 8(5)` ------->
`T\geq \$40`

`T\leq 8(25)` ------>
`T\leq \$200`

The domain of the function is the interval------->
`[5,25]`

`5\ hours \leq h \leq 25\ hours`

The range of the function is the interval------->
`[40,200]`

therefore

the answer is

the scale for the T-axis of her graph should go from
`0` to at least
`200`

The h-axis if her graph should go from
`0` to
`25`
