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?
As much as i would love two, im not good at that kind of math, im very sorry.
do you know anyone who could?
Do you know which number in the formula represents the growth rate?
3? i think
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%
would it be b?
nvm. I think the growth rate is 2 on the year. I think the formula's something like a(1 +r)^x
I'm not at all sure about this anymore. talked myself in circles :/
