Another model of population growth, say for cells of a tumor, is the differential equation for p(t) > 0. (a) The population is increasing p'(t) = 2p(t)in (p(t)) (b) The population is decreasing when p(t) > (c) Calculate the solution of the Gompertz model in implicit form. Note: Use p instead of p(t) for you solution. M when 0 < p(t) < -t+C
