TYPES OF FUNCTIONS In terms of relations, we can define the types of functions as One to one function or Injective function A function f P Q is said to be one to one if for each element of P there is a distinct element of Q. Many to one function A function which maps two or more elements of P to the same element of set Q.

Relations and Functions Class 12 Chapter 1 starts 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.

Therefore, this relation is not a function. Example 4 Is the relation expressed in the mapping diagram a function? If you think example 3 was bad, this example is the absolute worst! A single element in the domain is paired with four elements in the range. Remember, if an element in the domain is associated with more than one element in the

a relation of the form xfx, like x 3x 2 . The latter form is something special, and we will focus on that form next. 2 Functions and Their Properties A function is a relation where no two di erent ordered pair have the same rst coordinate. In our previous examples of relations, we have y 2x 2 a function y 2 a function n

3.5 Relations and Functions Basics A. Relations 1. A relation is a set of ordered pairs. For example, 2. Domain is the set of all rst coordinates so 3. Range is the set of all second coordinates so B. Functions A function is a relation that satises the following each -value is allowed onlyone -value Note above is not a function

Relation. Function. Definition. A relation is a connection between sets of values, often represented as a subset of the Cartesian product. A function is a relation in which each input is associated with exactly one output. Denotation. The symbol quotRquot is used to denote a relation. A function is represented by the symbols quotFquot or quotfquot. Example
