    "Find each of the indicated function value"

    implies you want 4²x - 5x + 9 = 2

    or do you want to find f(2) ?

    I have a feeling it is the second interpretation.
    if f(x) = 4²x - 5x + 9
    f(2) = 4(2)^2 - 5(2) + 9
    = 15

    f(-3a) = 4(-3a)^2 - 5(-3a) + 9
    = 36a^2 + 15a + 9

    Your next posting has the same kind of questions.
