For (b), the limiting value of the logistic growth function appears to be 29.47232081 but since the model deals with people, the limiting value requires to be rounded off. Thus the limiting value of the growth function is 29 people.
Finally, the physical interpretation of the mathematical can be interpreted as that eventually the population does not change.
