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

    \[\sqrt{0} = 0\]

    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.

    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.

    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.
