Question
The logistic curve is the graph of the function a f(x) = 1+ be-rx where a, b, and r are suitable parameters. describe, for example, the initial rapid growth of a population, followed by a slowdown of the growth as resources become sparse. Since e¯™ tends to zero as a This function may tends to infinity f(x) approaches . equals a as x tends to infinity, and at x = 0 the initial population a f(0) = 1+6 The rate r is the usual growth rate that would prevail indefinitely in the presence of unlimited resources. Suppose a = 4200, b = 10, and r = 0.01. Then the initial population is and as time goes on the population approaches but never quite reaches
