Which order pair could you remove from the relation {(-2,-,,,1),1,0)}

What's the point here?  Why would you remove one of the ordered pairs?

The only thing I see here that hints at an answer is that -1 is the first term of both (-1,1) and -1,0).  If we got rid of one of these, then the relationship could be a function; otherwise it is not a function.  Why?  Because in the case of a function, all first elements of the ordered pairs are unique (different from all the other first elements).

You have to put the answer options on here in order for us to know which statement to tell you is correct.
