Question

Consider the objective function: f(x,y) = 4x+3y, subject to the constraints:
x+y >= 7
-4x+10y <= 70
2x+4y <= 64
9x-7y <= 63
x+3y >= 3

The feasible set is a plygon with 4 vertices.
The maximum of f(x,y) is attained at the vertex with coordinates (__,__). The maximal value of f(x,y) is ___.
The minimum of f(x,y) is attained at the vertex with coordinates (__,__). The minimum value of f(x,y) is ___.
