4. Consider the following problem: Maximize Z = 4x1+ 2x2 subject to 2x1 <= 16(resource 1) x1 + 3x2 <= 17 (resource 2) X2 <= 5 (resource 3) and x1
>= 0, x2 >= 0. (a) Solve the problem graphically. (b) The objective function changes to Z = cx1+ 2x2. What is the range of c, when the optimal solution does not change?
