14. A species of freshwater fish called Perch was introduced into a large lake. The equation below can be used to model the number of Perch in the lake as a function of the number of months since the Perch were introduced. You can assume no Perch were in the lake before the introduction. P(t) = 4000(1.3-0.84¹) (a) How many Perch were introduced in the lake? (b) Evaluate lim P(t). t-x (c) When will there be 4400 Perch in the lake? Give an exact answer and an answer to the nearest tenth.
