Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!
The restriction here is that what is inside the square root must be greater than or equal to 0. So,
Please see my own non-traditional explanation of Functions, Domain, and Range. You can get to my own website by doing a "Bing" search for my last name "Rapalje". Look for "Rapalje Homepage" at the top of the search list. Near the top of my Homepage is a link "Math in Living Color". Click on this link, and look for "College Algebra", then "Chapter 2", and "Functions, Domain, and Range."
In addition, there is a video that I did in my classroom a few years ago that you can see. Go back to my Homepage and look for the link "Rapalje Videos." Click on either "Intermediate Algebra" or "College Algebra." These are two different videos presented at two different levels of explanation. These might be helpful to you--they are FREE!
