If an optimization engineer uses the Simplex method to maximize the tensile strength of a steel alloy, which result indicates the objective function is unbounded?

💡 Explanation

When using the Simplex method, an unbounded objective function is indicated by no feasible solution existing because the constraints do not allow an optimal value. Therefore, infeasibility indicates the function's unrestricted nature, rather than the objective value itself growing indefinitely or basis variables becoming zero.
