Biologists stocked a lake with 400 fish and estimated the maximal
population for the fish of that species in the lake to be 10,700. The
number of fish tripled in the first year. Assuming that the size of the
fish population satisfies the logistic equation, find an expression for
the size of the population aftert years.
