    Step-by-step explanation:

    f (x) = x^+4x+2 First, let's evaluate when x=3, x=4 and x=5.

    f (3) = 3²+4 (3) + 2 = 9 + 12 + 2 = 23

    f (4) = 4²+4 (4) + 2 = 16 + 16 + 2 = 34

    f (5) = 5²+4 (5) + 2 = 25 + 20 + 2 = 47

    Now, let's find the rate of change.

    34 - 23 = 11

    47 - 34 = 13

    Finally, the average rate of change.

    (11 + 13) / 2 = 12
