anonymous 5 years ago need help finding the domain!

1. anonymous

g(x)=$\sqrt[5]{-5x+9.6}$

2. amistre64

domain should be all Real numbers

3. amistre64

5root(x) has no limitations since it is an odd radical.

4. anonymous

An odd degree root allows you to have anything under the radical.

5. anonymous

thanks! What exactly does that mean I do next? Excuse my lack of understanding with this, but I missed class for this section. So it could be helpful if someone could help walk me through it! :)

6. amistre64

3root(-8) = -2 4root(-16) is undefined..

7. amistre64

if your looking for interval notation: Domain: (-inf,inf)

8. amistre64

other notation would be: Domain: {x|x is an element of R}

9. anonymous

yes I am looking for interval notation

10. anonymous

what is inf?

11. amistre64

$domian: (- \infty , \infty )$

12. amistre64

infinity

13. anonymous

ohh ok. So that would be the answer to this problem? I never know what exactly needs to be done with the numbers, but I noticed this was a common answer for some

14. amistre64

yep.... that would be the answer :)

15. anonymous

Thanks so much!

16. anonymous

actually, this is an online assignment and I just realized that I had put that answer and it told me that was the wrong format.. So they must be looking for another kind of answer. (it says to round any decimal values to two decimals.. so it could possibly be a number answer

17. anonymous

maybe it's because I didn't do the parenthesis

18. anonymous

yeah, that was it. Thanks again!
