The domain is a set containing all the x-coordinates.
The range is a set containing all the y-coordinates.
If the same x-coordinate or y-coordinate appears more than once, list it only once in the domain and range sets.

@mathstudent55 How do I check for the x & y coordinates?

mathstudent55 · Answer

In each ordered pair, the first number is the x-coordinate, and the second number is the y-coordinate.
