You can put this solution on YOUR website!

For part a), carefully examine all of your ordered pairs. If you can find at least one pair of ordered pairs where the first numbers are the same but the second numbers are different, the the relation is NOT a function. Otherwise it is a function.

For part b), the domain is the set of first numbers from all of the ordered pairs. In other words, all of the values.

For part c), the range is the set of second numbers from all of the ordered pairs. In other words, all of the values.
