  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(_____)

  2. f(3) = 2x + 4
    g(1) = 7x^2 – 6x + 9

  3. F(3)=9x+4 g(2)=7x^2-1x+5

    𝑓(3)=7𝑥+6 𝑔(2)=5𝑥^2−1𝑥+9

    𝑓(8)=6𝑥+4 𝑔(5)=2𝑥^2−1𝑥+7
