Question

Find the domain and range of the relation, and state whether or not the relation is a function. {(3,2), (3,1), (1,3)}

Answer 1

The domain is the x values and the range is the y values
The x values are the first numbers in the coordinate and the y values are the last numbers in the coordinate

For example:

In (3,2)
3 is the domain and 2 is the range.

Answer 2

This means that the Domain is 3,1 and the Range is 1,2,3

The set is not a function because the x value repeats itself.

Does that make sense?

Answer 3

thank you yes it does
