    Answer:

    (a) f(3) = 4

    (b) gf(3)​ = 13

    Step-by-step explanation:

    Given;

    f(x) = x + 1

    g(x) = x² – 3

    (a) Find f(3);

    f of 3 is calculated as;

    f(3) = (3) + 1

         = 4

    (b) Find gf(3)​;

    g of f of 3 is calculated as;

    f(3) = 4

    gf(3) = (4)² – 3

            = 16 – 3

            = 13
