I believe the answer is C
I read something in my textbook about all living organisms have history of the same genetic info =D
From the data given above, we can make the following:
N(0) = 2 x 3^0 = 2
N(1) = 2 x 3^1 = 6
N(2) = 2 x 3^2 = 18
An exponential function is represented by:
y = ab^x
where a is the initial value and b is the growth rate.
The exponential function for this case would be:
y = 2(3)^x
y = 6^x
