Simply replace each x with the given value of x.

When x = -2:

$8(-2)^3\\8(-8)\\\\=-64$

When x = -1:

$8(-1)^3\\8(-1)\\\\=-8$

When x = 0:

$8(0)^3\\8(0)\\\\=0$

When x = 3:

$8(3)^3\\8(27)\\\\=216$

OR you could use a graph for this, here is how the function is going to look:

Answer:

D) {-2, 1, 2, 5}

Step-by-step explanation:

The "output" of a function will never be an ordered pair, so we can immediately eliminate options A and B.

In this case, the output refers to the y-values of the function.

Since the ordered pairs are: (-2, 5), (-1, 1), (2, -2), and (5, 2), we see that the output of this function is: 5, 1, -2, 2.

Thus, choice D is correct.
