Which statement is correct about all functions?

Answer and explanation

Correct answer: Every function is a relation

A relation is a collection of ordered pairs that connects elements of one set with elements of another set. A function is a special relation with an additional rule: every element of the domain must have exactly one image in the codomain. Because every function satisfies the general definition of a relation, every function is necessarily a relation.

The reverse statement is not true. A relation may assign two different outputs to one input, or may fail to assign an output to some domain element, and then it is not a function. Being one-one is also not required for every function; different inputs may have the same output. Therefore option A is correct. The other choices either reverse the definition or impose conditions that do not apply to all functions.
