15. [Global Optimization] Find the global maximum and minimum values of the function on the given domain. Be sure to do the following: • Check for any critical points in the interior of the domain • Check for any critical points on the boundary curves of the domain (using parametrization) • Check the value of the function at the endpoints of the boundary curves (a) f(x, y) = x² + y² on the triangular region whose vertices are (3,0), (3,2), and (-1,2).

15. [Global Optimization] Find the global maximum and minimum values of the function on the given domain.
Be sure to do the following:
• Check for any critical points in the interior of the domain
• Check for any critical points on the boundary curves of the domain (using parametrization)
• Check the value of the function at the endpoints of the boundary curves
(a) f(x,y) = x² + y² on the triangular region whose vertices are (3,0), (3,2), and (-1,2).
(b) g(x, y) = xy on the disk a² + y² ≤ 4
(c) h(x, y) = 10 + 6y-2²-y² on the region where x² ≤ y ≤ 4.
