The function f(x) = 15(2)x represents the growth of a frog population every year in a remote swamp. Elizabeth wants to manipulate the formula to an equivalent form that calculates every half-year, not every year. Which function is correct for Elizabeth's purposes?

f(x) = 15(2 to the one half power)2x

f(x) = 15(2)the x over 2 power

f(x) = fifteen halves(2)x

f(x) = 30(2)x

Come on kelsey... All you do is divide it by 2. Does it need any more explanation? If you still never got it, the 3rd answer choice.

It's okay, I didn't mean to be mean. Anyway whenever it says something like full then half of that, you know you just divide the value of the full by 2. Okay? A lesson learned is a lesson learned at the end of the day...
