Question

Write an exponential growth function to model the situation. A population of 422,000 increases by 12% each year.

Answer 1

This is just like working with money in a bank account
that's earning 12% interest.

If the population is 422,000 today, and
' n ' is the number of years after today,
then

         Population  =  422,000 (1.12)ⁿ .
