**Steve**, Wednesday, April 11, 2012 at 12:09pmReview your material on linear optimization. The max or min value of f(x,y) is found to be at the vertices of the region defined by the constraints.

Here, the region is a triangle, with vertices at (0,0) (2,0) (0,4)

f(0,0) = 1

f(2,0) = -1

f(0,4) = 5
