Important Topics for NCERT Maths Exemplar Solutions Class 11 Chapter 2 – Relations and Functions

What is the Relation?

A relationship between sets of information is called a relation. For example, there are different boys in your class. The pairing of all the names and heights of the boys is a relation. In relations and functions, the pairs of names and heights are “ordered”, which means one boy comes first and the other boy comes second and so on.

What is a Function?

A function is a “well-mannered” relation. For example, the relationships you have with the members of your own family, some members of the family behave better to you with that compared to the other members of the family.

Cartesian Product of Sets

Let’s take two non-empty sets Q and R. So, the Cartesian product of Q and R is the set of all ordered pairs of elements from Q and R.

Q × R = {(q,r) : q Q, r R}

Let Q = {q1,q2,q3,q4} and R = {r1,r2}

Then, the Cartesian product of Q and R will be;

Q × R = {q1r1, q2r1, q3r1, q4r1, q1r2, q2r2, q3r2, q4r2}

For example: Let suppose, M = {a,b,c} and N = {1,2,3}

Therefore, M × N = {a 1, a 2, a 3, b 1, b 2, b 3, c 1, c 2, c 3}. This set has 8 ordered pairs. This can also be represented in a tabular form.
