Reconsider the model in Prob. 4.1-5. Follow the instructions of Prob. 4.2-1 for parts (a), (b), and (c).

(d) Repeat part (b) for the corner-point infeasible solutions and the corresponding basic infeasible solutions.

(e) Repeat part (c) for the basic infeasible solutions.

In problem

(a) Introduce slack variables in order to write the functional constraints in augmented form.

(b) For each CPF solution, identify the corresponding BF solution by calculating the values of the slack variables. For each BF solution, use the values of the variables to identify the nonbasic variables and the basic variables.
