Grade 8 Relations and Functions Worksheets

Relations and functions are completely new topics, but at the same time, some of the most important topics in grade 8. Relations and functions define a mapping between the elements of two sets that have an input and an output. They are represented using ordered pairs of the form (input, output). A relation in math is a set of ordered pairs that define the relationship between two sets. On the other hand, a function is a special type of relation in which each input only has one output. That means all functions are relations, but all relations are not functions. 

Relations and functions have some similarities and differences. But to understand and to easily tell them apart, students need practice. Practicing problems from the grade 8 relations and functions worksheets gives students an opportunity to understand the concept in detail. 

But before students proceed with practicing problems from the worksheet, they need to recollect the key points of the chapter. Students can get a quick recap from the following articles:

This page explains the concept of relations and functions and the differences between them with the help of some examples.

Frequently Asked Questions

Functions are special types of relations that follow a particular set of rules. So, a relation can be a function if it follows these rules. In other words, all relations are not functions. But all functions are relations.

A relation relates an input to an output. If every input of a relation has exactly one output, the relation is a function. As a result, all functions are relations, but not all relations are functions.

A function is a relation in which each input corresponds to one and only one output. Even if one output corresponds to 2 inputs, but if each input corresponds to only one output, then the relation is still a function.
