2. xy=k

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

-4^3 is -64
when you subtract a negative you are just adding
-64 + 4 = 60
Then you do the second one

-3^3 is -27
-27 + 3 is -24
Then the third one

-2^3 is -8
-8 + 2 is -6
Then the last one

-1^3 is -1
-1 + 1 = 0
Since we did not get -2 the answer is D
Hope this Helps!
