1 33

2 Answer

  • Answer:

    I believe it should be 3 23

  • Answer:

      2.5

    Step-by-step explanation:

    The rate of change can be found from the slope formula.

      m = (y2 -y1)/(x2 -x1)

    Using the first two lines of the table, we find ...

      m = (23 -18)/(-3 -(-5)) = 5/2

    The rate of change of the function is 5/2 = 2.5.
