Using Graph of Function

[nycmath]

Precalculus

Edition 10
Chapter 2, Section 2.3

The graph of f is given.
Use the graph to find:

A. The graph of a function f is given.
Use the graph to find:

A. The numbers, if any, at which f has a local maximum. What are the local maximum values.

B. The numbers, if any, at which f has a local minimum. What are the local minimum values.

See attachment.

[Eigenvalue]

A. Local maximum at x=0; the local maximum value is 1

B. Local minimum at x=π and x=-π; the local minimum is -1

C. y=cos(x)

[nycmath]

A. Local maximum at x=0; the local maximum value is 1

B. Local minimum at x=π and x=-π; the local minimum is -1

C. y=cos(x)

Correct.
