Question

The frog population at a lake doubles every three weeks. the population can be modeled by f(x) = 15(2)x and f(6) = 960. what does the 15 represent?

Answer 1

We have to answer what does the 15 represent in the function : f ( x ) = 15 * 2^x, which models the increasing of the frog population at a lake. We know that the frog population doubles every 3 weeks and that: f ( 6 ) = 960. It means that: 15 * 2^ 6 = 15 * 64 = 960. And also f ( 0 ) = 15 * 2^0 = 15 * 1 = 15. Therefore it is a starting population.



Answer: The 15 represent - The starting population.
