Hello, jigger1!
With a population problem, we assume an exponential function: .The population of a herd of elk was 220 in 1970 and 530 in 1990.
What is the population today?
In 1970
. . We have:.
The function (so far) is: .
In 1990
. . We have: .
Take logs: .
. .
Hence, the function is: .
Today , we have: .
