Alex started a new social media account, which he uses to post pictures of cute animals. On the first day, he had only \( 8 \) followers. However, his account became popular very quickly and his number of followers tripled every day. Identify the recursive function that gives the number of followers he has after \( n \) days.

A) \( f ( n ) = \left\{ \begin{array} { l } { f ( 1 ) = 3 } \\ { f ( n ) = 8 f ( n - 1 ) if n > 1 } \end{array} \right.\)

B) \( f ( n ) = \left\{ \begin{array} { l } { f ( 1 ) = 8 } \\ { f ( n ) = f ( n - 1 ) + 3 if n > 1 } \end{array} \right.\)

C) \(f ( n ) = \left\{ \begin{array} { l } { f ( 1 ) = 3 } \\ { f ( n ) = f ( n - 1 ) + 8 if n > 1 } \end{array} \right.\)

D) \(f ( n ) = \left\{ \begin{array} { l } { f ( 1 ) = 8 } \\ { f ( n ) = 3 f ( n - 1 ) if n > 1 } \end{array} \right.\)
