DId my previous explanation make sense to you?

anonymous · Answer

I don't understand why you keeep posting identical questions

anonymous · Answer

(1, 2)  (3, 2) --> What's the value if x=1? It's 2.  What's the value if X=4? It's 2.  Since you can always answer the question, it's a function.

(1, 8) (1, 9) --> What's the value if x=1? You don't know.  it could be either 8 or 9.  Therefore it's not a function.
