So, go ahead and check the Important Notes for Class 12 Maths Functions Let A and B be .two non-empty sets, then a function f from set A to set B is a rule which associates each element of A to a unique element of B. Operation Table: When the number of elements in a set is small, then we can express a binary operation on the set through a table, called the operation table. i.e. The syntax of import statement is as follows: Lets examine a few widely used modules and the functions that are contained in such modules: Save my name, email, and website in this browser for the next time I comment. There is a well defined accessibility for each variable. or xRy, yRz xRz, x, y,z R. Equivalence Relation: A relation R defined on a set A is said to be an equivalence relation if R is reflexive, symmetric and transitive. Only the function or block where it is defined can access it. f = { (1,1), (2,2), (3,3)}. Bijective or One-one and Onto Function: A function f : X Y is said to be a bijective function if it is both one-one and onto. The elements of X are called the domain of f and the elements of Y are called the codomain of f. The image of the element of X is called the range of X which is a subset of Y. A formal parameter, i.e. 1: Relations and Functions: Types of relations: reflexive, symmetric, transitive and equivalence relations. Hence, a function may or may not have parameters.
