    Answer: 5

    Step-by-step explanation:

    g (x) = 6 - x

    g (-3) = 6 - (-3)

    = 6 + 3

    = 9

    f (x) = x - 4 f (g (-3)) = f (9)

    f (9) = 9 - 4

    = 5

    f (g (-3)) = 5

    Step-by-step explanation:

    To find f (g (x)) just plug in g (x) for x in f (x)

    f (x) = x - 4

    f (g (x)) = (6 - x) - 4

    f (g (x)) = 6 - x - 4

    f (g (x)) = 2 - x

    Now to find f (g (-3)) we plug in - 3 for x.

    f (g (-3)) = 2 - (-3)

    f (g (-3)) = 2 + 3

    f (g (-3)) = 5
