The population of a town is 75 000 and decreases 15% each year. Complete the exponential function that models the population afterx years f(x) = 75,000
Answers: 3
where a is the initial value and (1 - r) is the growth rate (which in our case is a decay, actually!). Our initial value is 75000 and our rate of change in the population is 15% or .15. Filling in our model:
and simplifying:
This turns out to be a decay problem because the value inside the parenthesis is less than 100%.
