Step-by-step explanation: The easiest way to tell whether or not this relation is a function is to look at the x-coordinates of the given ordered pairs.

If any of the ordered pairs in this relation have the

same x-coordinate, then the relation is not a function.

In the last relation, all the x-coordinates are different.

So we can say the last relation is a function.
