## Answers ( )

Answer:The correct option is

(A).Step-by-step explanation:The function representing the growth of number, in billions, of the DNA sequences in a database x years since 2010 is:

The general growth function can be represented as:

Here,

y= final valuea= initial valuer= growth ratet= timeCom-paring the two functions we get:

This implies that the annual increase rate in number, in billions, of the DNA sequences is

32%.Thus, the correct option is

(A).
