The "Theys" are gonna get me, so get the points while they're hot!

F(x) = x^2 - 16

Step-by-step explanation:

The average profit from the sale of 1 piece of furniture = x+4.

The average # of pieces of furniture that can be made using the current supply of raw materials = x - 4.

The average profit = The average profit from the sale of 1 piece × The average number of pices that can be made.

Therefore,

F(x) = (x+4) (x-4)

Use the difference of squares formula:

F(x) = x^2 - 4^2

F(x) = x^2 - 16
