Which of the relations is not a function?

Which of the following is not true?*Every function from the set A to the set B is a relation from the set A to the set B.If f is a function from A to B and (a, b) ∈ f, then f(a) = b, where a is called the pre-image of b under f.Every relation from the set A to the set B is a function from the set A to the set B.If f is a function from A to B and (a, b) ∈ f, then f(a) = b, where b is called the image of a under f.
