Question 354629: I was wondering if someone can help me. I have a couple questions that I need to know how to do. The directions say, determine whether each relation is a function. Give the domain and range for each relation.
{(1,2), (3,4), (5,5)}
I need to show my work, and I have no idea where to get started. Any help you can provide is greatly appreciated!
Tahnks so much!

You can put this solution on YOUR website! Hi,
{(1,2), (3,4), (5,5)}
*Note: To qualify as being a function, each x value must result in a unique value of y. This relation satisfies that.
.
domain would be {1,3,5 } and the range would be {2,4,5}
