Question d please
Sketch the feasible cone D. and the cone of descent F at (x, y) = (0,0), and find their intersection, in all the following cases: (a) f(x,y) = x+y, S = {x ≥ 0, y ≥ 0} y ≥ 0} (b) f(x, y) = x-y, S = {x ≥ 0, (c) f(x,y) = x + y, S = {x ≥ 0, (d) f(x, y) = x - y, S = {x ≥ 0, y ≥ 0, y ≤ x²} y ≥ 0, y ≤a²}
