    Step-by-step explanation:

    set F function in g function:

    gof (x) = (5x-4) 2

    simplified:

    gof (x) = 10x-8

    put 2 in function

    gof (2) = 10 (2) - 8 = > 20-8 = > 12

    Step-by-step explanation:

    (g•f) (2) = g (f (2))

    Since f (x) = 5x - 4

    f (2) = 5 (2) - 4 = 10 - 4 = 6

    (g•f) (2) = g (f (2))

    g (f (2)) = g (6) = (6) ^2 = 36
