Answer:

(f - g)(x) = 11x²

(f - g)(0) = 0

Step-by-step explanation:

To find (f - g)(x), you need to subtract g(x) from f(x).

f(x) = 4x²

g(x) = -7x²

(f - g)(x) = 4x² - (-7x²)

(f - g)(x) = 4x² + 7x²

(f - g)(x) = 11x²

Now that you have (f - g)(x), solve for (f - g)(0).  Plug in 0 wherever there's an x.

(f - g)(x) = 11x²

(f - g)(0) = 11(0)²

(f - g)(0) = 11(0)

(f - g)(0) = 0
