5-147.
A function f is continuous over the interval [2, 8] and has values that are given in the table at right. Homework Help ✎
Using the sub-intervals [2, 5], [5, 7], and [7, 8], what is the trapezoidal approximation of
? 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).
x | f (x) |
2 | 10 |
5 | 30 |
7 | 40 |
8 | 20 |
