How Do You Figure Out If a Relation is a Function?

A relation is a set of ordered pairs
We've created an x-y table to help us look at the domain and range
The x-coordinates go in the left column and the y-coordinates go in the right column
Since there are no repeats in the x-column, our relation is a function

1. The x-column contains the x-coordinates and the y-column contains the y-coordinates
1. Our relation is the set: {(0,2), (3,4), (-3,-2), (2,4)}
1. The x-column contains the x-coordinates and the y-column contains the y-coordinates
1. Our relation is the set: {(0,2), (3,4), (-3,-2), (2,4)}
1. The domain is the set of x-coordinates and the range is the set of y-coordinates
1. The domain is listed in the x-column
1. The domain is listed in the x-column
1. This is the definition of a function
1. This is the definition of a function
1. A relation is a set of ordered pairs

Determine whether the following relation is a function. {(0,2), (3,4), (-3,-2), (2,4)}
