A certain forest covers an area of 2000 square kilometers. Suppose that each year this area decreases by 6%. What is the function that best represents the area of the forest each year and how much area remains after 12 years?

Best possible function would be an exponential function

f (x) = b*a^x

Because each year it decreases with %

Possible function would be

f (x) = 2000*0.94^x

f (x) is how big the forest would be after x amount of years

(a = 0.94

a = 1 + r

r = - 6% = - 0.06)

After 12 years it would look like

f (12) = 2000*0.94^12 = 951.84 square km
