How to solve for the boundary points

Find the exact extreme values of the function
: = f (x, y) = (x – 5)² + (y – 1)² + 28
-
subject to the following constraints:
0 <x < 16
0 < y< 10
Start by listing all nine candidates, including their z values, in the form (x,y,z):
First, list the four corner points and order your answers from smallest to largest x, then from smallest to largest y.
