Functions are an important part of discrete mathematics. This article is all about functions, their types, and other details of functions. A function assigns exactly one element of a set to each element of the other set. Functions are the rules that assign one input to one output.
1.1: An Overview of Discrete Mathematics
What is discrete mathematics? Roughly speaking, it is the study of discrete objects. Here, discrete means “containingdistinct or unconnected elements.” Examples include: Determining whether a mathematical argument is logically correct. Studying the relationship between finite sets. Counting the number of ways to arrange objects in a ...

A function is a rule that assigns each input exactly one output. We call the output the image of the input. The set of all inputs for a function is called the domain. The set of all allowable outputs is called the codomain. We would write f: X → Y to describe a function with name , f, domain X and codomain . Y.

Definition (Proposition) A proposition is a declarativesentenceorstatementhas a truthvalue. It is a statement which is either true or false. Each proposition has a “truth value”: either true or false.
6.2: Definition of Functions - Mathematics LibreTexts
Definition. Let \(A\) and \(B\) be nonemptysets. A function from \(A\) to \(B\) is a rule that assigns to every element of \(A\) a unique element in \(B\). We call \(A\) the domain, and \(B\) the codomain, of the function. If the function is called \(f\), we write \(f :A \to B\).

A Course in Discrete Structures - Department of Computer Science
Discrete mathematics deals with objects that come in discrete bundles, e.g., 1 or 2 babies. In contrast, continuous mathematics deals with objects that vary continuously, e.g., 3.42 inches from a wall. Think of digital watches versus analog watches (ones where the second hand loops around continuously without stopping).

Discrete mathematics - Wikipedia
Discrete mathematics is the study of mathematical structures that can be considered "discrete" (in a way analogous to discrete variables, having a bijection with the set of natural numbers) rather than "continuous" (analogously to continuous functions).
