f(x) = x^1/3
ok so for this project I have to identify all this stuff for the function
$f(x) = x^{1/3}$

and a few things that I have to identify I don't know.

1) What are intervals of continuity?
2) Explain one-to-one

I have no idea what both those things are. Please explain for me so that I can understand.

Thanks!

I think you are being asked to provide what interval fr x these function is continuous. As x can be any real number in this case then the interval for continuity would be $(-\infty ,\infty)$

The term one to one means that there is only one x value for any y value (and vice versa) for the function in question.
