How do you do it?

Say the problem .

The critical points are only a few.

How do you figure out whether this is the absolute or local without looking at the graph?

Thank you.

has no critical points...er, unless you count where it's undefined as a critical point, which would be at x = 0. but that would not be an absolute or local max or min. so all you have left to do is check the endpoints. the one that gives the larger value is the absolute max and the one that gives the smaller value is the absolute min
