In five years, a garden festival plans on using the park where Iris has been studying the invasive snails. Explain to the garden festival committee how to find the average rate of change for the snail population between years 2 and 5. Describe what this average rate of change represents.
Here's the math
f(2)=200(1.03)^2(2)= 225
f(3)=200(1.03)^2(3)=238
f(4)=200(1.03)^2(4)=253
f(5)=200(1.03)^2(5)=268
