    A: 0 because if you replace all the x's with 2 you would have 2^2-2*2 which equals 4-4=0

    This is stating that, if x was 2, what is the answer to the equation.

    So basically, the equation is 2^2 - 2 (2) = ?

    The first step is 2 squared, which is 4, then you subtract 2 (2) or 4. So 4-4 is 0.

    The value of f (2) is 0

    A would be correct.
