Given
(3,6) (3,7) (-2,-5) (-9,11)
First of all we have to define both terms: Relation and Function
A relation is a set of ordered pairs containing one element from each set
A relation can be a function only if there is no repetition in domain i.e. no first element in each ordered pair should be repeated.
In the given set of ordered pairs, they are relation as all the ordered pairs have two values.
While the given relation is not a function, as there is repetition in first elements of two ordered pairs i.e. 3 is repeated in (3,6) (3,7)
Hence,
It is a relation but not a function
