Well, a function has only one y-value for every x-value. For example, y = √x is not a function because if x = 36, y = 6 and -6.
Can you think of any x-value that would result in more than one y-value?

Yes! There comes a point where we have to tell the student to study similar questions that were already answered, and then apply the same reasoning to try to answer this question, rather than continue to post similar questions.
