    the answer is still 3

    if u graph f(x) = 3 you get a straight line
    so f(x) = 3 for all real numbers

    By "f(x) = 3", do you mean "f(x) = 3 for all x"?

    he probably meant f(x) = 3 for all x
    otherwise it would've been f(a) = 3......

    Assuming he wrote it correctly, that's all it could mean!

    In case you come across a similar problem, f(x-ct) translates f(x) to the right by ct.
