Answer
The absolute maximum is located: $(1;1)$ (also a stationary point)
The absolute minimum is located: $(-2;-1)$ (also a stationary point)
Work Step by Step
We can locate all the extrema by looking at the graph:
a relative extremum can be identified if there exists an interval where the point is the maximum or minimum.
An absolute extremum can be identfied if on the whole interval the point is the maximum or minimum.
The stationary point is where the function stops increasing or decreasing.
The absolute maximum is located: $(1;1)$ (also a stationary point)
The absolute minimum is located: $(-2;-1)$ (also a stationary point)
