    (g o h) (5) = 4

    Step-by-step explanation:

    h (x) = x - 7

    g (x) = x^2

    (g o h) (5) = ?

    (g o h) (x) = g (h (x)) = (x - 7) ^2

    (g o h) (5) = (5 - 7) ^2 = (-2) ^2 = 4

    g°h (5) = 4

    Step-by-step explanation:

    g°h (5) = g (h (5))

    h (5) = 5-7=-2

    g (-2) = (-2) ^2=2^2=4
