    Step-by-step explanation:

    First evaluate f (4) then substitute the value obtained into g (x)

    f (4) = 4 - 7 = - 3

    g ( - 3) = ( - 3) ² = 9

    ⇒g (f (4)) = 9

    g (f (4))) = 9

    Step-by-step explanation:

    f (x) x-7

    f (4) = 4-7=-3

    g (f (4))) = (x-7) ^2>3^2=9

    g (f (4))) = 9
