A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
The graph represents the relation, but not a function.
This is relation, because it defines the rule for each some
such, that the ordered pair (x,y) lies on the graph.
This is not a function, because for all input values of x (excluding x=3) we can find two different output values of y.
