Write an example of an equation for an exponential growth function.

Answer 1

f(x) = a b^x

If b > 1, it is exponential growth

a = initial value

Example:

f(x) = 1000 (1.30)^x

This function may represent a population that started at 1000, then increased by 30% each year, where x is the number of years elapsed since it was 1000.
