Which among the relation is a function?

A function is a relation which describes that there should be only one output for each input (or) we can say that a special kind of relation (a set of ordered pairs), which follows a rule i.e., every X-value should be associated with only one y-value is called a function.

How do you identify if the relation is a function?

Identify the input values. Identify the output values. If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.

What are the 3 types of relation of function?

There are different types of relations and functions such as empty relation, universal relation, reflexive relation, symmetric relation, transitive relation, equivalence relation, constant function, polynomial function, identity function, on-to-one function, onto function, bijective function, etc.
