Find the absolute maximum and minimum vales of the set D.

F(x,y) = x^2 + y^2 - 2x, D is the closed triangular region with vertices (2,0), (0,2), and (0,-2).

I know that I have to find Fx(x,y) and Fy(x,y) but I'm not sure where to go from there. Any help is appreciated.

Fx(x,y) = x -1; Fy(x,y) = 2y
