    Exponential means you can find a common ratio between terms

    a ratio is the n+1 term divided by the nth term a common difference like +2 means a linear function: it goes up by 2 at each term

    g looks like a common ratio of 0.7 0.7^x h(x) looks like 1.6^(x+3) k(x) looks like a parabola (it goes down, then back up)
