This week I learned how to determine the domain or range of a graph, or in an x-chart, or in any way that shows the x values and y values of the relation.

All the x values are the domain and the y values are the range.

Which means that for example, if I were to be given the numbers (1,2) (3,4) (5,6) (7,8) the domain would be {1,3,5,7} and the range would be {2,4,6,8}.

If you have a question where a number in the x value or the y value is repeated more than once, you only have to write it once when doing it’s domain or range. For example: (1,2) (1,3) (2,3) (3,4) the domain would be {1,2,3} and the range is {2,3,4}.
