A 2-column table with 4 rows. The first column is labeled x with entries negative 6, negative 1, 0, 3. The second column is labeled y with entries negative 7, 1, 9, negative 2.
A
{x | x = –6, –1, 0, 3}B
{y | y = –7, –2, 1, 9}C
{x | x = –7, –6, –2, –1, 0, 1, 3, 9}D
{y | y = –7, –6, –2, –1, 0, 1, 3, 9}23

Which recursive formula can be used to generate the sequence shown, where f(1) = 9.6 and n > 1?9.6, –4.8, 2.4, –1.2, 0.6, ...
A
f(n + 1) = (–0.5)f(n)B
f(n + 1) = (0.5)f(n)C
f(n + 1) = f(0.5n)D
f(n + 1) = f(–0.5n)25
