Answer:

Step-by-step explanation:

No, ( -5, 6) ( -2, 0) ( 0, 6) ( 0, 2) ( 1, -3) do not make up a function. It does not pass the vertical line test when graphed, as there are 2 points, (-5, 6), and (0, 6), that lines up on the same y-value.

Hello!

For this you can plug in the x values in the choices and see if you get the y value

y = $-4^{3} - (-4)$

-4^3 is -64

when you subtract a negative you are just adding

-64 + 4 = 60

Then you do the second one

$y = -3^{3} - (-3)$

-3^3 is -27

-27 + 3 is -24

Then the third one

$y = -2^{3} - (-2)$

-2^3 is -8

-8 + 2 is -6

Then the last one

$y = -1^{3} - (-1)$

-1^3 is -1

-1 + 1 = 0

Since we did not get -2 the answer is D

Hope this Helps!
