      Model I - Exponential Growth and Decay. In class, we have seen the exponential model for growth and decay: dy/dt = ky. where k > 0 for exponential growth and k < 0 for exponential decay. This model says that the rate of change of y with respect to t is directly proportional to the amount of y present at time t.

      k = relative growth rate that is constant. t = the time the population grows. P(t) = what the population grows to after time t. Notes [1. When modeling a population with an exponential growth model, if the relative growth rate k is unknown, it should be determined. This is usually done using the known population at two particular times. 2.
