Question

HELP!!! WILL GIVE MEDAL!!
The function f(x) = 4(4)x represents the growth of a fly population every year in a remote swamp. Jackie wants to manipulate the formula to an equivalent form that calculates three times a year, not just once a year. Which function is correct for Jackie's purpose, and what is the new growth rate?

f(x) = 4(4)x; growth rate 400%
f(x) = 4(4)3x, growth rate 4%
f(x) = 4(1.59)3x; growth rate 59%
f(x) = 4(1.59)x; growth rate 4%

Answer 1

Well, looking at f(x)=4(4)x , it would make sense to represent a growth 3 times per year with f(x)=4(4)3x because the exponent x is going to be 3 times grater, since you triple the yearly growth.

Answer 2

Ok but is it correct?

Answer 3

Yes
