a -39
b -15
c 15
d 39

which one is the correct answer ?

So x^3 -3y when x = -3 and y =4 will be 

(-3)^3 -3*4 = -27 -12 = - 39

hope thsi will help you 

so choice A is right sure 

If you would like to solve x^3 - 3 * y when x = - 3 and y = 4, you can do this using the following steps:

x = - 3
y = 4
x^3 - 3 * y = (-3)^3 - 3 * 4 = -27 - 12 = - 39

The correct result would be A -39.
