    12.6

    Step-by-step explanation:

    Given the function, F (x) = 20/4+3e-0.2x

    Where e is an exponential function,

    To get f (3), we need to substitute x = 3 into the given function

    F (3) = 20/4 + 3e - 0.2 (3)

    f (3) = 5 + 3e - 0.6

    f (3) = 4.4+3e

    Substituting the value of e = 2.718

    f (3) = 4.4+3 (2.718)

    f (3) = 12.554

    f (3) = 12.6 to the nearest tenth.
