Step-by-step explanation:
We first check the critical points on the interior of the domain using the
first derivative test.


The only solution to this system of equations is the point (0, 4), which lies in the domain.


is a saddle point.
Boundary points - 
Along boundary 





Values of f(x) at these points.

Therefore, the absolute maximum and minimum is
