Let S F X Y 2x 3 Xy 2 5x 2 2y 2 A Find The Critcal Ordered Pairs For The Functio

Let’s f(x,y)=2×3+xy2+5×2+2y2.

a)Find the critcal ordered pairs for the function, and use the D-test to determine if each is a relative maximum, relative minimum, or a saddle point.

b) Find the absolute maximum and absolute minmum of the function f over the triagular region with vertices (-3,-3) (3,-3) (3,3)
