In mathematics, a function is a fundamental concept that describes a relationship between two sets, typically called the domain and the codomain.
It assigns each element in the domain to a unique element in the codomain, following a specific rule or formula. Functions are often represented as f(x), where “x” is an input value, and “f(x)” is the corresponding output.
Functions are used to model various real-world processes, solve equations, and analyze data.
They play a crucial role in mathematics, science, engineering, and many other fields.
