O as the number of units of output increases, the labor hours per unit increase in a corresponding, observable, linear
relationship.
O as the number of units of output decreases, the labor hours per unit decline in a corresponding, observable, linear
relationship.
O as the number of units of output increases, the labor hours per unit decline in a corresponding, observable, nonlinear
relationship.
