HI!!

7. misty1212

which one are you doing?

8. anonymous

I need help on all 4

9. misty1212

1 doen't make any sense, they all have a domain and range

10. misty1212

2) the domain is $(-\infty, 0)\cup (0,\infty)$

11. misty1212

cause 0 is not in it range is $(-3,\infty)$

Oh okay, I missed the U in the domain, I was unsure if it would be C. or B. Thank you!

@Night-Watcher I think #1 is C. #2 is C #3 is D
