  1. f(x) = 3x + 5

    f(x) = 6x^2 + 1

    g(x) = 22 - 8x^3

    H(x) = 14x^2 + 52x^3 - 8√x

    It can really be any algebraic expression. A function is defined as "a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output."

    For example, in f(x) = 3x + 5

    f(1) = 3(1) + 5 = 8
    f(8) = 3(8) + 5 = 29

    (i.e. you just substitute the values of x).
