#D#: All real x

#R#: All real y

You can best do this by graphing the equation and seeing the domain and range through that:

graph{x^3 [-101.4, 101.4, -50.7, 50.7]}

As you can see, the graph has no asymptotes and extends infinitely both across the x- and y-axis.

Therefore:

#D#: All real x

#R#: All real y
