    5x + 11

    Step-by-step explanation:

    We are subtracting function g (x) from function f (x).

    Write f (x) as is: f (x) = x + 8.

    Then change all of the signs of g (x) : - g (x) = 4x + 3.

    Now combine like terms for the sum (f - g) (x) = x + 8 + 4x + 3. We get

    (f - g) (x) = 5x + 11
