Section 1 - Question 6 Sarah is conducting a science experiment where she initially has a population of 4 fruit flies. Every week the population triples. She writes the function f (x) = 4(3)" to predict the population growth Which rule can also model the function? A An = 3 + An-1, A1 = 4 An = 3* An-1, A1 = 4 B. с An = 4 + An-1, A1 = 3 D An = 4* An-1, A1 = 3 ​
