9x

Step-by-step explanation:

Divide x from both equations on both sides to isolate the f and the g. Then, calculate to find f and g alone.

f = 4 + 1 = 5.

g = 1^2 - 5 = 1 - 5 = - 4.

Subtract g from f, and you get 9. Finally multiply this product by x to find the answer to the expression (f-g) (x).
