Question is the picture:

Consider the following problem, where the value of c has not yet been ascertained. a. Draw the feasible region. You should draw each line by generating arbitrary points, and report these points in your answer. (10 marks) b. Use graphical analysis to determine the optimal solution(s) for the various possible values of c, -0 a, . Then, for each range, you should say that the model is unbounded or bounded for all values of c in that range. If the model is bounded, you should also say if it has a specific single optimal solution, or it has multiple optimal solutions on a specific line for all values of c in that range.] (15 marks) Max Z = cx, + 2x2 subject to X -2x, 50 X +x, 56 2x, +3x, 23 x 20,x, 20
