I know the answer but how I should enter it?

minimum : (0,-4) ( red mark)

maximum: (3,5) (green mark)

Explanation

An absolute maximum point is a point where the function obtains its greatest possible value. Similarly, an absolute minimum point is a point where the function obtains its least possible value.

so, we need to check the graph

minimum : (0,-4) ( red mark)

maximum: (3,5) (green mark)

I hope this helps you
