Assume that a population was 853 when t=0, and 3 years later it became 2314.

Question

Assuming the population grows exponentially, write a formula for the size of the population in t years:
Population =
What is the population when t = 12?:

Answer 1

clearly,
p = 853*e^(kt)
so, since
p(3) = 2314, k = 1/3 log(2314/853) = .3326577
