Relations and Functions Class 12 Chapter 1 stats with the revision of general notation of relations and functions.Students have already learned about domain, codomain and range in class 11 along with the various types of specific real-valued functions and the respective graphs. Exercise 1.1 : Solutions of Questions on Page Number : 5. Equivalence relations, different types of functions, composition and inverse of functions. We can also write it as R ⊆ {(x, y) ∈ X × Y : xRy}. Q25. This is the reason you should study this chapter carefully, and solve every problem on your own including solved examples. Reflexive Relation Examples. Ex 1.1, 1 Determine whether each of the following relations are reflexive, symmetric and transitive: (i)Relation R in the set A = {1, 2, 3…13, 14} defined as R = {(x, y): 3x − y = 0} R = {(x, y): 3x − y = 0} So, 3x – y = 0 3x = y y = 3x where x, y ∈ A ∴ R = {(1, 3), (2, 6), Indeed, y is the son or the daughter of y. ∴(y, x) ∉ R ∴ R is not symmetric. Example 1: A relation R on set A (set of integers) is defined by “x R y if 5x + 9x is divisible by 7x” for all x, y ∈ A. ∴R is not reflexive.
