b)The local maximum is about 31.627417. The local minimum is about –13.627417.

c)The local maximum is about 13.627417. The local minimum is about –31.627417.

d)The local maximum is about 22.627417. The local minimum is about –22.627417.

**Dr Russ**, Monday, July 21, 2008 at 11:10amThere is no need for a calculator.

The min or max are at x=+/-sqrt(2)

so I get

Maximum is 32.62742 (x=-(2^0.5)

Minimum is -13.6274 (x=2^0.5)

which is a)

But check my working.
