Relations and Functions Worksheet

What is Relation?

Relations can be described as a set of ordered pairs. Let’s look at some examples of relation, such as:

  • {(1,0) , (25,50)}
  • {(Mon, Sun) , (Tue, Sat)}

Where { } denotes the symbol of a set.

A relation is the correspondence among two or sets (known as the domain and range) such that there are one or more elements assigned to every element or member of the domain.

Example 1

(2,4), (2,3), (3,7), (5,2) is a relation of

Domain {2,3,5}

Range {2,3,4,7}

What is Function?

A function is defined as a correspondence among two sets known as the domain and the range such that there is exactly one element of the range assigned to every element of the domain.

Example 2

(3,3), (2,1), (4,3), (6,5) is a function of

Domain {2, 3, 4, 6}

Range {1, 3, 5}

We bring you Relations and functions worksheet that include problems based on exponential functions, types of relationships and types of functions along with inverse trig functions with solutions to every math problems.

Practise This Question

Polyurethane is quite good for cold weather for jackets and blankets. However, thermal emergency blankets or space blankets are often made up of something similar to aluminum foil and used by astronauts to avoid hypothermia when stuck in subzero temperature. Why do you think it is a good choice?
