# How do you find the domain and range of x^3?

It is $\setminus m a t h \boldsymbol{R}$.
the positive integer powers, like ${x}^{3}$ can be calculated for any value of the variable. In other words you can assign any value to $x$ and you will be able to calculate its cube.
For this reason the domain are all the real numbers $\setminus m a t h \boldsymbol{R}$.
