$y=\sqrt{2x+6}$

3. freckles

you don't want any negatives inside there you want 2x+6 to be positive or zero that means you want 2x+6 to be greater than 0 or equal to 0 that means you need to solve 2x+6>=0

4. anonymous

umm okay...

5. freckles

umm okay... is an interesting response

6. freckles

what does it that really mean

7. anonymous

it means i have no idea wat u just said

8. freckles

oh I would have no way of knowing that

9. freckles

do you know what positive or zero means?

10. anonymous

yes

11. freckles

means >0 or =0 right?

12. anonymous

okay..

13. freckles

if something is positive it is always greater than 0 if something is 0 it is equal to 0 we wanted 2x+6 to be positive or zero so we wanted 2x+6>=0

14. freckles

solving 2x+6>=0 will give you the domain

15. anonymous

okay

16. freckles

in pretty math symbols $\text{ you need to solve } 2x+6 \ge 0$

17. anonymous

r u gonna help me or just sit there?

18. freckles

I didn't know you required further assistance

19. freckles

you first want to isolate the 2x part

20. freckles

try subtracting 6 on both sides

21. anonymous

i completely suck at math andneed an answer

22. freckles

let me see what you have after subtracting 6 on both sides

23. anonymous

x=-3?

24. freckles

well don't forget you had an inequality not and equation

25. freckles

2x+6>=0 subtract 6 on both sides 2x>=-6 divide 2 on both sides x>=-3

26. freckles
