Funcions

Funcions, also known as functions, are fundamental building blocks in mathematics and computer science. In mathematics, a function is a relation between a set of inputs, called the domain, and a set of possible outputs, called the codomain, in such a way that each input is related to exactly one output. This relationship is often represented by an equation, such as f(x) = x^2, where 'f' denotes the function, 'x' is the input variable, and 'x^2' is the output. The domain of this function would be all real numbers, and its codomain could also be all real numbers.

In computer programming, a function is a named block of code that performs a specific task. Functions are used to organize code, make it reusable, and improve readability. They can accept inputs, known as arguments or parameters, and can return a value. For example, a function named `add_numbers` might take two numbers as input and return their sum. This modular approach to programming allows for the creation of complex applications by breaking them down into smaller, manageable components. Understanding functions is crucial for both mathematical problem-solving and software development.
