anonymous · Answer

im not sure if B would also be correct the wording is weird soo its confusing me

Cube roots are nothing.  Unless something REALLY spacial is going on, both Domain and Range are $\mathbb{R}$.

Really, any ODD root or power is like this.  It's the EVEN roots and powers you have to watch!

There you go, then.  Part of the learning of mathematics is the confidence to know you are done.  Move on to the next one.
