Question

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 6 represent?

The population after six weeks

The starting population

The rate the population increases

The number of weeks that have passed

Answer 1

Well since the question states per week, this is our variable since we will be dependent on how many weeks have passed

So f(6) will be the population after 6 weeks

Answer 2
