No I currently do not

Is it okay for me to help? I saw that you commented someone's name

- some.random.cool.kid

yes hero is a mod here and really brilliant but he doesn't respond to much people So if you think you got this I wont stop you lol

- stefrheart

Ah I understand :) Do you understand the domain and range?

- some.random.cool.kid

I know exactly what it is my trouble is finding it on the complex quad graphs so explaining that to me would do me alot of beneficial favors.

- stefrheart

Well based on this graph there seems to be no restrictions that is stopping the graph in both the x and y axis.

- some.random.cool.kid

indeed its just asking me to figure the domain and range for it whats bad is that they threw a wild graph at me and I am not sure what any of the points can be... my main struggle is figuring out where it meets I guess ...

- anonymous

you can take the cubed root of anything

- some.random.cool.kid

?

- anonymous

so domain is all real numbers

- stefrheart

You dont need any points for this graph for finding the domain and range

- stefrheart

\[(-\infty,\infty)\]

- some.random.cool.kid

yes ik that but I cant put that for the graph

- some.random.cool.kid

Im not sure that what its telling me to put when it says find the domain?

- some.random.cool.kid

thats way to easy ..

- stefrheart

I know it seems easy but that is the answer... all cube root functions without restrictions have a domain and range of all real numbers. There is nothing else to put besides all real numbers

- some.random.cool.kid

WOW really thanks! :~> so what about the range?

- some.random.cool.kid

same i assume?

- stefrheart

Hahahaha welcome! You are correct, the range is the same! :)

- some.random.cool.kid

just put the variables for it?

- some.random.cool.kid

ok

- stefrheart

Variables?

- some.random.cool.kid

i mean the -x -y?

- stefrheart

If you are doing the interval notation is \[(-\infty,\infty)\] and if not then it is xER

- stefrheart

or yER for range

- some.random.cool.kid

k thanks bye !D

- stefrheart

Welcome! Glad to be of help!! :D
