Question

In 2004, a specific species of

birds had a population of 1000.
About three years later, the
population was 216.
Write an exponential function
p(t)=a(b) that represents the
population t years after 2004.

Answer 1

Below

Explanation:

Pop = 1000 ( y)^t when t = 3

216 = 1000 ( y)^3

216/1000 = y^3

y = cubrt(216/1000) = .6

so the equation becomes

P(t) = 1000 ( .6^t) where t is # years past 2004
