    The function f(x) = 4(3)x represents the growth of a dragonfly population every year in a remote swamp. Erin wants to manipulate the formula to an equivalent form that calculates four times a year, not just once a year. Which function is correct for Erin's purpose, and what is the new growth rate?

    Do you know which number in the formula represents the growth rate?

    right, so if it's 3 for the whole year, divide it by 4 to get the growth rate every quarter

    these are my choices f(x) = 4(3)x; growth rate 300% f(x) = 4(3)x, growth rate 4% f(x) = 4(1.32)x; growth rate 4% f(x) = 4(1.32)4x; growth rate 32%

    @angiepangie0726 Is the formula an exponential? If it is you need to put the ^ sign to show that it is an exponential function. f(x)=4(3^x) is the same as \(f(x)=4(3^x)\)

    nvm. I think the growth rate is 2 on the year. I think the formula's something like a(1 +r)^x
