what have you done with this problem?

Absolute max or min is where first derivative is zero.

So absolute max or min can be at or . But to find out which one which you plug-in the values into the function and find out which one's larger than the other.

Now plug-in and separately into you'll find that

The function has absolute max at

And has absolute min at

You can check it in the following graph to be sure:
