Q. 38 For each graph of f in Exercises... [FREE SOLUTION]

Chapter 3: Q. 38 (page 248)

For each graph of f in Exercises 37鈥�40, explain why f satisfies the hypotheses of Rolle鈥檚 Theorem on the given interval [a, b]. Then approximate any values c 鈭� (a, b) that satisfy the conclusion of Rolle鈥檚 Theorem.
[a, b] = [鈭�3, 3]

Short Answer

Expert verified

The hypothesis of Rolle's theorem is satisfied because from the graph of f appears to be continuous on $[- 3, 3]$ and differentiable on $(- 3, 3)$ . The values of c that satisfy the conclusion of Rolle's theorem are $c 鈮� - 2.6, c 鈮� - 0.5, c 鈮� 2.3$ .

Step by step solution

Step 1. Given information.

Consider the graph of f for the interval $[- 3, 3]$ .

-3,3

Step 2. Satisfy hypothesis of Rolle's theorem.

It can be observed that the given graph has no break, hole or gap in the interval

[- 3, 3]

. So, the graph of f appears to be continuous on

[- 3, 3]

It can be observed that the graph has no corner, no vertical line or no discontinuous point in the interval $(- 3, 3)$ . So, the graph of f appears to be differentiable on $(- 3, 3)$ .

Thus, the hypothesis of Rolle's theorem is satisfied.

Step 3. Find values of c.

From the graph, $f (- 3) = 0$ and $f (3) = 0$ .

$鈬� f (- 3) = f (3)$

So, Rolle's theorem applies. There exists some $c 鈭� (- 3, 3)$ such that $f' (c) = 0$ or the graph has horizontal tangent line.

From the graph, such values of c where the graph has horizontal tangent line are $c 鈮� - 2.6, c 鈮� - 0.5, c 鈮� 2.3$ .
