A 2-column table with 9 rows. The first column is labeled x with entries negative 8, negative 6, negative 4, negative 2, 0, 2, 4, 6. The second column is labeled f of x with entries negative 16, negative 8, 0, 8, 16, 32, 64, 128. Which could be the entire interval over which the function, f(x), is negative?

(–8, –2)
(–8, 0)
(–∞, –6)
(–∞, –4)
