The function f(x) = 396(3)x represents the growth of a dragonfly population every year in a remote swamp. Pierre wants to manipulate the formula to an equivalent form that calculates every month, not every year. Which function is correct for Pierre's purposes?

Best ResponseYou've already chosen the best response.0**absent typos**: \(\large 396(3^{\frac{1}{12}})^{12x} = 396(3^{\frac{1}{12} \times 12x}) = 396(3)^{x}\) ie back to where you started. plug a number in and see. none of these look right https://gyazo.com/5b74d0c9b3753f89f9467f1bc3f2858c

Best ResponseYou've already chosen the best response.0f(x) = 33(3)x f(x) = 396(312)the x over 12 power f(x) = 396(3 to the one twelfth power)12x f(x) = 4752(3)x

Best ResponseYou've already chosen the best response.0this is the 2nd time I have seen one of these questions and they don't make much sense to me... I'd expect for this exponential model if the time changes to months the value of x needs to be divided by 12 so you can test by looking at the model \[f(1) = 396(3)^{\frac{1}{12}}\] then find f(2) and f(3) to see if there is growth hope it helps

Best ResponseYou've already chosen the best response.0well remember the index law for power of a power, multiply the powers \[(x^a)^b = x^{a \times b}\] so you have \[3^{\frac{x}{12}} = (3^?)^x\]
