Question 1157208: A study is done on the population of a certain fish species in a lake. Suppose that the population size P(t) after t years is given by the following exponential function.
P(t)=400(1.29)^t
Find the intial population size.
Does the function represent growth or decay?
By what percent does the population size change each year?
