What is the example of relation and 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….For example:
| Domain | Range |
|---|---|
| -1 | -3 |
| 1 | 3 |
| 3 | 9 |
What are the 3 types of relation of function?
There are different types of relations namely reflexive, symmetric, transitive and anti symmetric which are defined and explained as follows through real life examples.

What is a function give 5 examples?
The function is a relationship between the “input,” or the number put in for x, and the “output,” or the answer. So the relationship between 20 and 60, for example can be described as “3 times 30 is 60.” While the most common notation for functions is f(x), the actual notation can vary….Functions Examples.
| f(10) | 950 |
|---|---|
| f(5) | 450 |
What is function in our daily life?
Think of any process where an input produces an output; that process is a function. Here’s a few examples. Functions in the real world. A soda, snack, or stamp machine the user puts in money, punches a specific button, and a specific item drops into the output slot. (The function rule is the product price.

A one-to-one relationship exists when each row in one table has only one related row in a second table. For example, a business might decide to assign one office to exactly one employee. Thus, one employee can have only one office.
What are two examples of functions?
Example 2: Number of children We could define a function where the domain X is again the set of people but the codomain is a set of numbers. For example, let the codomain Y be the set of whole numbers and define the function c so that for any person x, the function output c(x) is the number of children of the person x.
What is a function give two example?
We could define a function where the domain X is again the set of people but the codomain is a set of numbers. For example, let the codomain Y be the set of whole numbers and define the function c so that for any person x, the function output c(x) is the number of children of the person x.
What is relation in real life?
Relations and Functions in real life give us the link between any two entities. In our daily life, we come across many patterns and links that characterize relations such as a relation between a father and a son, brother and sister, etc.
What are the examples of one-to-one functions?
A one-to-one function is a function of which the answers never repeat. For example, the function f(x) = x + 1 is a one-to-one function because it produces a different answer for every input.
What is function write an example?
A function is a block of statements that performs a specific task. Let’s say you are writing a C program and you need to perform a same task in that program more than once. In such case you have two options: a) Use the same set of statements every time you want to perform the task.
