Example 1: The collection of vowels in English alphabets. This set containing five elements, namely a,e,i,o,u. Example 2: A collection of favourite singers is not a set because it varies from person to person. If a is an element of a set A, then we write a   A and say a belongs to A or a is in A or a is member of A. If a does not belongs to A, we write a   A. Example 3: ‘a’ belongs to the set of vowels in English alphabets. Example 4: The collection of all states in the Indian union is a set. ...

In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and co-domain or range. A function is generally denoted by   where   is the input. The general representation of a function is . Definitions: 1. Write the definition of a mapping. Let A and B be two non-empty sets. A relation f from A to B, i.e., a subset of , is called a function (or a mapping or a map) from A to B if     I. ...
