What is written in this post,  is soup of words,

and a person who created it,  suffers of misunderstanding of what he  (or she)  writes.



<pre>
First statement in the post is INCORRECT.

It is incorrect, because NOT EACH set of ordered pairs represents a function.


For example, this set of ordered pairs  (1,2), (1,3), (1,4) does not represent a function.



Fortunately, the concrete set of ordered pairs, presented in the post, does really represent a function, saving the meaning.
