5-147.
  1. The function f is continuous on the closed interval [2, 8] and has values that are in the table to the right. Homework Help ✎

    1. Using the sub-intervals [2, 5], [5, 7] and [7, 8], what is the trapezoidal approximation of ?

    2. On what sub-interval is the average slope a minimum?

    I) [2, 5]

    II) [5, 7]

    III) [7, 8]

Test all answer choices and choose the lowest value. Recall that average slope is akin to saying average rate of change (AROC).
