1. The set of all natural numbers: {1,2,3,4,…}
2. The set of all vowels in the English alphabet: {a,e, i,o,u}
3. The set of all students in a class:{s1,s2,s3,…}

RELATIONS: Relations are connections or associations between components of two sets. Studies of the relationships between the components of various sets are done using relations, which can be displayed as tables, graphs, or matrices.

Examples:

1. The relation “is less than” between the sets of natural numbers and natural numbers: {(a,b)∈N×N∣a<b}
2. The relation “is equal to” between the sets of vowels in the English alphabet and the students in a class:{(v,s)∈{a,e, I,o,u} x {s1,s2,s3,…}| v= s1 for some i}
3. The relation “is a parent of” between the sets of students in a class and the students in a class: {(s1,s2)∈ {s1,s2,s3,…} X {s1,s2,s3,…} | s1 is a parent of s2}

FUNCTIONS: A function from a set A to a set B is a relation between A and B such that every element of A is related to exactly one element of B.

In other words, a function is a relation that maps each element of its domain (setA) to exactly one element of its codomain (setB).

Examples

1. The function that assigns to each natural number its square: f(n)=n2.
2. The function that assigns to each vowel in the English alphabet its number of occurrences in the word “hello”: g(v)=∣number of occurrences of v in “hello.”
