The frog population at a lake doubles every week. the population can be modeled by
f(x)=15(2)x
and
f(6)=960

what does the 2 represent?

a. the population after 6 weeks
b. the starting population
c. the rate the population increases
d. the number of weeks that have passed

The answer is C. The rate the population increases. The 960 in the equation represents the population at a certain number of weeks which is x. The starting population describes the quantity 15. The number of weeks that have passed is described as the 6 weeks. 

The equation would be described as: f(x) =15*(2^x) and f(x) =960
