    Answer:

    Rate = -10

    Step-by-step explanation:

    Given

    The table

    Required

    The average rate if change over (4,6)

    This is calculated as:

    Rate = \frac{f(6) - f(4)}{6-4}

    Rate = \frac{f(6) - f(4)}{2}

    From the table:

    f(6) = -37

    f(4) = -17

    So:

    Rate = \frac{-37 --17}{2}

    Rate = \frac{-37 +17}{2}

    Rate = \frac{-20}{2}

    Rate = -10
