sktjell 2 years ago WHAT IS The range of 3 √ x !?!?! PLEASE PLEASE PLAESE PLAESE I BEGGG I BEGGGGGGG! LOL

1. Kainui

What can x be? What numbers can you not take the square root of?

2. sktjell

O?

3. eigenschmeigen

$\sqrt{0} = 0$

4. Kainui

You can take the square root of 0, since 0*0=0. You can't divide by 0, don't forget that when determining range and domain.

5. sktjell

YES BUT LET ME SHOW U GUYS THE OPTIONS

6. Kainui

Try turning off your caps lock, it doesn't really help you.

7. eigenschmeigen

$\sqrt{-1} \notin R$

8. sktjell

o sorry lol :)

9. sktjell

10. eigenschmeigen

what types of numbers can we not square root?

11. Kainui

Haha it's fine. So yes, eigenschmeigen is right, if you can guess what that means. Remember that a domain is all the numbers of x you can choose to satisfy an equation while the range is all the numbers you can have as a result of your domain.

12. sktjell

i attached a picture of the options can u guys check it out

13. Kainui

Numbers in these brackets [x,y] mean that they are included in the range or domain. Numbers in parenthesis (x,y) mean that they're not included, but every number between them is.

14. sktjell

can u guys help because he didnt help :(

15. imagreencat

Well, what do you think the answer is?

16. eigenschmeigen

@Kainui i personally think you were explaining very well

17. sktjell

C ?

18. eigenschmeigen

what happens if you put a negative number for x?

19. sktjell

@eigenschmeigen im just very slow in math like i dont get anything im sorry and i need to get this half a credit graduate with my class by june 3rd and its a whole bunch of quizes this invluded and im just stressing! :(((

20. eigenschmeigen

what happens if we put a negative number in for x?

21. eigenschmeigen

what do we get, for example, if i put in -16

22. sktjell

i believe the answer is A.

23. A.Avinash_Goutham

A....

24. eigenschmeigen

yes you would be correct

25. sktjell

thanks so much.

26. imagreencat

I hope you're not just guessing and you truly, genuinely understand the concept behind your answer.
