WebMar 24, 2024 · Definition: Function. Let A and B be nonempty sets. 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 → B. Given x ∈ A, its associated element in B is called its image under f. WebNotation can be defined as a system of symbols or signs that denote elements such as phrases, numbers, words etc. Therefore, function notation is a way in which a function …
