(1 point) Suppose the size of a population at time t is N(t), and the growth rate of the population is given by the logistic growth function =1r'N(1), t>0 dt K where :r' and K are positive constants. That is, the growth rate of the population is a function of the population size, given by N f(N)=rN(1E), N>0. Compute f'(N). f' (N) : r-{2rN)fK When is the growth rate increasing, and when is the growth rate decreasing? f(N) is increasing for N in f(N) is decreasing for N in
