No.

Try to created a table or a graph for the equation:

y = 0 when x is rational,

and

y = 1 when x is irrational for 0 < x < 1.


Remember, between any two rational numbers (no matter how close), there are infinitely many Irrational Numbers, and between any two irrational numbers (no matter how close), there are infinitely many rational numbers.

Is a relation always a function or is a function always a relation?

A function is always a relation, but a relation is not always a function. In mathematics, a relation is a set of ordered pairs, while a function is a specific type of relation where each input (or domain element) is associated with exactly one output (or range element). Therefore, while all functions meet the criteria of being a relation, not all relations satisfy the conditions to be classified as functions.
