Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Initial population of rabbits = A = 6
Each year, there were 4 times as many rabbits as the year before.
i.e. b = 4
Let the number of years be x.
So, our required equation will be
[tex]f(x)=Ab^x=6(4)^x[/tex]
Hence, Option 'D' is correct.
