Homework Help: Functional equation problem ( edited )

  1. Oct 8, 2014 #1
    Let f : R -> R be a continuous function such that,
    f(x) - 2f(x/2) + f(x/4) = x^2
    . f(3) = ?

    Answer to be calculated in terms of f(0).

    I am puzzled on how to approach such problems. Some insight would be greatly appreciated.
