(1). Consider the following contraints: 21-2 20 21-2 3 71 6 22 4 120 #2 20 (a). Sketch the e region. (b). For the objective function max z = (c). For the objective function max z = (i) The LP has a unique optimal solution (ii) The LP has multiple (alternative) optimal solutions (iii) The LP is infeasible (iv) The LP is unbounded (d). State an objective function that will have multiple optimal solutions for the above contraints (1) (2) (3) (5) 1+ 22 what is the optiomal solution? State the values of z, 21, 22. +2 which of the 4 cases do we have (see page 67 of textbook):
