A discrete function is a function where both the domain and range can be listed as distinct elements in a set. This is in comparison to a continuous function like a line.

Learn how to find the domain and range of a discrete relation from a graph, and see examples that walk through sample problems step-by-step for you to improve your math knowledge and skills.

Since the range is all 𝑦 y -values, look from the bottom to the top for the least to greatest values. The smallest 𝑦 y -value is 0, and then the line continues up forever.

Jan 1, 2026 · These number systems are very important when the domain and range of a relation are described using interval notation. A relation is said to be discrete if there are a finite number of data …

May 19, 2025 · In this article, we will take a deep dive into the process of finding the range of discrete functions using systematic approaches. Whether you are a student, educator, or professional …

In its simplest form the domain is all the values that go into a function, and the range is all the values that come out.

From there, we started to talk about all of the different ways we could represent a discrete relation, and how we find the domain and range from each representation.

All of the values that can go into a relation or function (input) are called the domain. All of the values that come out of a relation or function (output) are called the range. Range may also be referred to as …

Dec 11, 2025 · A function represents a relationship between a set of inputs (domain) and their corresponding outputs (range), where each input has exactly one output. Domain: The set of all …

This comprehensive article will delve deep into the concepts of domain and range in discrete math, exploring their definitions, how to identify them for various types of functions, and their significance in …
