N(t) = 25t + 150 for 0< =t< 6, (200 + 80t)/(2 + 0.05t) for t> =8

the number of fish in a pond at time t years is modeled by the function n defined above, where f is a continuous function such that f(0)=80.

a) find limt→[infinity]n(t). explain the meaning of limt→[infinity]n(t) in the context of the problem.
