Question:

A common model for population growth uses the logistic (or sigmoid) curve. Consider the logistic curve in the figure, where P(t) is the population at time t ≥ 0.

a. At approximately what time is the rate of growth P' the greatest?

b. Is P' positive or negative for t ≥ 0?

c. Is P' an increasing or decreasing function of time (or neither)?

d. Sketch the graph of P'. You do not need a scale on the vertical axis.
