Question

can someone explain the steps to finding absolute extrema?

Answer 1

The absolute extreme occur when the derivative of the function is equal to 0.

Answer 2

So take the derivative of f(x) and set it equal to 0 .

Answer 3

Solve for f'(x) = 0 and you have your x values for the local extreme.

Answer 4

Substitute those x values back into the function and you have your point's of extreme values.

Answer 5

you substitute back into the original function?

Answer 6

That's the process for relative extrema. Absolute extrema might occur at end points on the interval if there are no critical points.

Answer 7

Well then you have to check for that don't you? ;) .

Answer 8

Yep.

Answer 9

thanks!
