What is a Function? Definition Types and Notation – BYJUS
A function in maths is a special relationship among the inputs (i.e. the domain) and their outputs (known as the codomain) where each input has exactly one output and the output can be traced back to its input. Types of Functions in Maths An example of a simple function is f (x) = x 2.
What is a Function – Math is Fun
A function relates an input to an output. It is like a machine that has an input and an output. And the output is related somehow to the input. Input Relationship Output We will see many ways to think about functions but there are always three main parts The input The relationship The output Example Multiply by 2 is a very simple function.
