    Answer:

    39

    Step-by-step explanation:

    Find the value of f(x) at both points

    f(3) = 3(3)³ + 1 = 82

    f(1) = 3(1)³ + 1 =  4

    —————————

    Average Rate of Change is just like slope

    Divide the change in f(x) by the change in x

    r = (82 – 4) / (3 – 1)

    r = 78/2

    r = 39
