A function f is continuous over the interval [2, 8] and has values that are given in the table at right. Homework Help ✎

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

  2. Over which 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).
