Step-by-step explanation:
If you can draw any vertical line which intersects the graph more than once then the graph does not represent a function.
The intersection shows that for a given value of x in the domain there is more than one value of f(x). So this is a one-to-many relation and is not a function because a function must be one-to-one or many-to one.
