Relations and Functions Class 12 chapter 1 recalls the notion of relations and functions, range, domain and co-domain have been introduced in class 11 along with the different types of specific real-valued functions and graphs. In class 12 Maths, we will learn about the different types of relations and functions in detail. Learn about ordered-pair numbers, relations and an introduction to functions, Algebra: What are relations and functions, How to determine whether a relation is a function, how to use a mapping and the vertical line test, how to work with function notation, examples and step by step solutions.

This video looks at relations and functions. It includes six examples of determining whether a relation is a function, using the vertical line test and by looking for repeated x values. Is the relation given by the set of ordered pairs shown below a function? So before we even attempt to do this problem, right here, let's just remind ourselves what a relation is and what type of relations can be functions. So in a relation, you have a set of numbers that you can kind of view as the input into the relation. We call that the domain.

In NCERT Solutions for Class 11 maths chapter 2 relations and functions, we learn about ordered pair, cartesian product of sets, relations, representation of a relation, function as a special kind of relation, function as a correspondence, equal functions, real functions, domain of real functions, some standard real functions and their graphs, operations on real functions. 6 Relations and Orderings 53 function from Y into X, then there is a one-to-one function from X onto Y. 3. If X is a subset of the real numbers, then either there is a one-to-one in the book. Although Elementary Set Theory is well-known and straightforward, the modern subject, Axiomatic Set Theory, is both conceptually more diﬃcult.

Relations and functions book and Functions (Mathematics) Relations A relation is a set of ordered pairs, usually defined by some sort of rule. It can be plotted onto the number plane. The domain is the set of all the first elements (abscissae) of the ordered pairs (the permitted x values if graphing the relation).
