    I agree with the above method, f (-3) which from the form of f (x), in which the x is where you plug into the rest of the equation which x^2. So (-3) ^2 and will become positive, usually the parenthesis is indication it will be positive once squared.

    D. 9

    Step-by-step explanation:

    First, plug in - 3 for the value of x in your function. You will get

    f (-3) = (-3) ^2

    The square of any real number is always positive. Thus, (-3) ^2 = (-3) * (-3), or 9.
