Algebra 2 ! 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?

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)4^x; growth rate 32%
