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
