some.random.cool.kid one year ago What are the domain and range for the cube root function graphed below? Justify your answer in complete sentences.

@Hero

2. some.random.cool.kid

3. stefrheart

4. some.random.cool.kid

No I currently do not

5. stefrheart

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

6. 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

7. stefrheart

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

8. 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.

9. stefrheart

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

10. 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 ...

11. anonymous

you can take the cubed root of anything

12. some.random.cool.kid

?

13. anonymous

so domain is all real numbers

14. stefrheart

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

15. stefrheart

$(-\infty,\infty)$

16. some.random.cool.kid

yes ik that but I cant put that for the graph

17. some.random.cool.kid

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

18. some.random.cool.kid

thats way to easy ..

19. 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

20. some.random.cool.kid

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

21. some.random.cool.kid

same i assume?

22. stefrheart

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

23. some.random.cool.kid

just put the variables for it?

24. some.random.cool.kid

ok

25. stefrheart

Variables?

26. some.random.cool.kid

i mean the -x -y?

27. stefrheart

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

28. stefrheart

or yER for range

29. some.random.cool.kid

k thanks bye !D

30. stefrheart

Welcome! Glad to be of help!! :D
