Domain and Range - YourTeacher.com - Algebra Help

For a complete lesson on domain and range, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that the form (x, y) that is used to represent a point is called an ordered pair, and a relation is a set of ordered pairs, such as {(5, -1), (0, 3), (-3, 4), (3, 4)}. Students also learn that the domain is the set of all x-coordinates, which in this case is {5, 0, -3, 3}, and the range is the set of all y-coordinates, which in this case is {-1, 3, 4}. Finally, students learn to write a rule for a given relation, or find the domain and range when given a rule for the relation.

@Joey57900 Bueller...Bueller...Bueller...­Bueller...Bueller...Bueller...­Bueller... He's the shit though. He's helping me with my college course. At least he doesn't have a high-pitched, whiny, and nasally voice. :P

@EmzaRamen

You should also know how to spell "know". ( You dont spell it, "now")

[EmzaRamen]

All I needed to know was which was x and which was y! I'm an 8th grader in geometry. I should now this xP

[Joey57900]

could this guy have an more of a dull voice T_T

@MRvidioMAN the same thing happened to me today :( But except the domain and range on my homework isn't exactly like the one in this video, but at least I can try it with knowing just a little about it... XD I hate it when teachers expect you to be able to do something when you have no knowledge about it...it's such a drag DX
