A 2-column table with 7 rows. The first column is labeled x with entries negative 5, negative 3, negative 1, 1, 3, 5, 7. The second column is labeled f of x with entries 8, 4, 0, negative 2, negative 2, 0, 4.

Question

Which is a valid prediction about the continuous function f(x)?

f(x) ≥ 0 over the interval [5, ∞).
f(x) ≤ 0 over the interval [–1, ∞).
f(x) > 0 over the interval (–∞, 1).
f(x) < 0 over the interval (–∞. –1).

Answer 1

just examine the choices.
(a) is ok, because it works for x=5,7
(b) fails because f(7) = 4
(c) fails because f(-1) = 0
(d) fails because f(-5) = 8

Answer 2

what is the answer

Answer 3

i think its B

Answer 4

The table represents a function.

A 2-column table with 5 rows. The first column is labeled x with entries negative 6, 7, 4, 3, negative 5. The second column is labeled f of x with entries 8, 3, negative 5, negative 2, 12.

Which value is an output of the function?

–6
–2
4
7
7
