Funkciji

Funkciji is a term that can refer to a few different concepts depending on the context, most commonly in mathematics or programming. In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. This relationship is often described by a rule or formula. For instance, the function f(x) = x^2 takes any number x and squares it to produce an output. The set of all possible inputs is called the domain, and the set of all possible outputs is called the range. Functions are fundamental to calculus, algebra, and many other branches of mathematics, used to model relationships and solve problems.

In programming, a function is a block of organized, reusable code that is used to perform a single, related action. Functions provide better modularity for applications and a low degree of code duplication. They are also referred to as subroutines, procedures, or methods in different programming languages. When a function is invoked, the program flow jumps to the function code, executes the statements within it, and then returns to the point where the function was called. This allows developers to break down complex programs into smaller, manageable pieces, improving readability and maintainability. The concept of functions is central to procedural and object-oriented programming paradigms.
