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: .
