Match the problem with the clue. Hint: only use clues one time. Some of the constraints have negative coefficients. Problem is unbounded No feasible solution Multiple optimal solutions 5 Redundant constraints Match each of the options above to the items below No area of the graph is true for all constraints. in a maximization problem, there is no constraint that keeps the objective function line (soprofit line) from going to infinity One or more constraints exist that do not form part of the feasible region. The objective function has the same slope as one of the constraints, and this constraint is at the optimal limit of the feasible region
