Answer: Choice A) [tex]-\infty < x < \infty[/tex]
We can plug in any x value we want. The domain is the set of all real numbers. We don't have to worry about applying the square root of a negative value since negative values are allowed in cube roots.
For instance, [tex]\sqrt[3]{-64} = \sqrt[3]{(-4)^3} = -4[/tex]
