Well what is your guess openstudy does not let us just give out answers

herb12 · Answer

@meganmhall0517 Openstudy is a community site that anyone can contribute to. and where you can discover, share and add your knowledge to help other students succeed, if you are making posts to annoy other people, that is going completely against the meaning of open-study. please think before you post, and question if it is contribution or taking away from someones opportunity to learn.

@Herb12 Don't think they were trying to annoy them, just help them in a way which would be more beneficial than just giving the answer. 

The range of the given set of ordered pairs is the list or a set containing the values of the second element (y) or the ordinate. In more simple terms, it's all the y values. Does that help you work out the answer OP?
