Question

Asked Oct 26, 2019

The function *f* has a continuous second derivative, and it satisfies *f*(7)=5, *f*′(7)=4 and *f*″(7)=−2.

We can conclude that:

**A.** *f *has a local maximum at 7**B. ***f* has neither a local maximum nor a local minimum at 7**C. ***f* has a local minimum at 7**D. **We cannot determine if A, B, or C hold without more information.

Step 1

f"(7)=-2

Since f " (7) < 0 so ...
