What is relation and function in class 12?

It is a special kind of relation(a set of ordered pairs) which obeys a rule, i.e. every y-value should be connected to only one y-value. Mathematically, “a relation f from a set A to a set B is said to be a function if every element of set A has one and only one image in set B”.

How many exercises are there in relation and function class 12?

NCERT Solutions for Class 12 Maths Chapter 1 Relations and Functions has 55 questions in 4 exercises.

What are into functions Class 12?

Onto (Surjective) Function. A function f: X -> Y is said to be an onto function, if every element of Y is an image of some element of set X under f, i.e for every y ∈ Y there exists an element x in X such that f(x) = y. Properties: The range of functions should be equal to the codomain.

What is function class 12 computer science?

A function can be defined as a single related task, which is written as a block of codes. It only runs when it is called. We can pass data to the function when we call a function, these are known as parameters. A function can return data as a result of using the return statement.
