    Lightbulb Function table

    x....f(x)....g(x)....h(x)
    0.....1.......5
    1.....0.......2
    2.....5.......3
    3.....2.......1
    4.....3.......4
    5.....4.......8

    basically you have to look up the values from the table, h(x)=f(g(x) so for x=0:

    g(0)=5
    f(5)=4

    so h(0)=4

    this works for all but the last value which according to the problem statement f(8) is out of the domain.
