Well know, the following relation is not a function. Do you want to know why?

What is the function value when x=1 ???

What they're trying to get at Erica is that in order for a relation to be a function you must be able to predict the value without ambiguity. If x = 1, then the ordered pair (1, -2) says the value is "-2" but also, the ordered pair (1, 3) says when x = 1 the value is "3". So if someone asks what the value is, you don't know whether to say -1 or 3. That makes this relation NOT a function. A function would have only one value for any particular "x" and that one value would ALWAYS be the same.
