Class 6 - Class 7 - Class 8 - Class 9 Class 10 - Class 11 - Class 12 . b) Suppose Y = f gconsists of a single element. Class 12 Maths Notes Chapter 1 Relations and Functions. ��Ç�����.*����! The operations that ensue, in order to obtain a result for the following pair of elements such a, b from X to another element of X is called as a binary operation. A function f : X → Y is one-one (or injective) if f(x1) = f(x2) ⇒ x1 = x2 ∀ x1 , x2 ∈ X. The characteristic function of a set S, considered as a subset of some larger domain D, is defined as follows: FS: D Æ {0,1} : FS (x) = 1 iff x Œ S FS (x) = 0 otherwise There is a one-to-one correspondence between sets and their characteristic functions. 0000001764 00000 n An operation ∗ on X is commutative if a ∗ b = b ∗ a ∀ a, b in X. 0000008040 00000 n Download the FREE PDF of Relations and Functions Class 12 Notes and start your preparation with Vidyakul!
