    First we need to find inverse function of f (x) which is written in a form of (f (x)) ^ (-1)

    That means that we are actually looking for function f (y) and we need to solve this equation for "y"

    y = (4x + 1) / 3

    3y = 4x + 1

    4x = 3y - 1

    x = (3y - 1) / 4

    f (y) = (3y - 1) / 4

    Now we simply put the value of 3 instead of y and find the answer:

    f (y=3) = (3*3-1) / 4 = 2

    Answer is 2
