painting is fx=5x+12.

a. How will the graph of this function change if

b. How will the graph of this function change if
the hourly charge is lowered to $4?

Answer 1

A) $87

B) $13

Explanation:

Sorry if it's wrong, there's no graph and the frame cost can't really change.

5x+12

A) 5(15)+12= $87

B) (5-4)+12= $13
