No, the problem is not unbounded. Even though the feasible region extends infinitely, the objective function has a finite best value at a corner point. A problem is only unbounded if the objective can improve indefinitely without reaching a finite optimum.

No, it is not unbounded because the objective function reaches a best value at a corner point. An unbounded problem would allow the objective function to keep improving without limit.

No. The problem is not unbounded because the objective function has a finite best value at a corner point.

An unbounded problem occurs when the objective value can continue increasing (for maximization) or decreasing (for minimization) indefinitely. The feasible region can extend infinitely while the optimal solution is still bounded.

No, the problem is not unbounded. A linear program is considered unbounded only when the objective function value can reach positive or negative infinity within the feasible region. 

No, the problem is not unbounded because the objective function reaches a best value at a corner point. A problem is unbounded only if the objective function can continue improving indefinitely without reaching a finite optimal value.

No. A feasible region can be unbounded while the LP still has a finite optimal solution. The problem is only called unbounded if the objective function can continue improving indefinitely along an unbounded direction without violating the constraints. If the objective reaches its best value at a corner point and cannot improve beyond it, the problem has a finite optimum even though the feasible region extends infinitely.
