A new species of fish is introduced into a lake, and the fish population grows rapidly. The growth of their population is modeled by the exponential function P(t) = 10(b)t , where t is the time in weeks after the release and b is a positive unknown base. After observing the population growth over a few weeks, the exponential function P(t) = 10(3)t is used to model the growth.
