The usual exponential growth equation is given by:
y = C * e^kt, where k greater than 0.
t is the number of years, in this case (2005 - 2000), t = 5 years
C is a constant at x = 0
k is the growth constant
There will be two equations:
2104 million = C * e^k(0)
so, C = 2104 million, the other equation is:
3881 million = 2104 million * e^k(5)
solve for k:
k= 0.12245
The exponential growth equation is:
y = 2104 million * e^(0.12245*t)
