This is not a function because any value
I choose for +x+, here are 2 values
possible for +y+, positive and negative.
---------------------------------------
In order to be a function +y+=+f%28x%29+ , there must
be a unique +y+ for each +x+
--------------------------------
For instance:
+x+=+1+
+y+=+1+ and +y+=+-1+
