Answer 1

First, every time when you ask question like this about function you must give elements of the initial set.

Definition of the function is - Every element of the starting set (domain- x)

must be related to only one element of the second set ( codomain-range-y).

In your case you have element (coordinate) x=3 which is in the relation with two elements (coordinates) y=2 and y=5 and that is relation but not function.

Good luck!!!

Answer 2

The answer to your question is,

No. It is not a function. Reasoning behind this is because there are repeating numerators. You can NOT have two of the same numerator as that will not form correctly if graphed. Two threes.
