  1. I think the format is confusing, and the answer uses incorrect notation and the two functions are, in fact, never “equivalent”. Rephrase like this?

    Fill in spaces with whole numbers 1 – 9 only one time, so that the final equality is correct.
    f(x) = ___ x + _____
    g(x) = ___ x^2 – ____x + _____
    f(____) = g(_____)
