A relation is a function if every value in the domain is mapped to only one value in the range. A non-mathematical example is mothers. Leaving aside surrogacy, every person has only one mother. Therefore the relation f(x) = x's mother is a function. But f(x) = x's ancestor is not a function because everyone has loads of ancestors. They may not all be known but that is not relevant.

Good question. A relation is simply that; any x-value to create any y-value. A function, however, cannot be defined for multiple values of x. In other words, for a relation to be a function, it must have singular values for all x within its domain.

they were actually a grandmom,mom and a daughter....so mom is daughter 2 grand mom and she herself has got a daughter..so 2 moms n 2 daughters...

A relation has pairs of numbers. A function is a special relation where for each input there is one and only one output.

In mathematics the difference between a function and a relation is that each X-value in a function only has a single Y-value.
