I searched Google under the key words "math domain range" to get these possible sources:
http://mathforum.org/library/drmath/view/54551.html
http://www.purplemath.com/modules/fcns2.htm
http://www.freemathhelp.com/domain-range.html
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
