A function, in mathematics, 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 is the only way that a function can be defined, without any ambiguity. The input is called the argument of the function, and the output is called the value of the function. A function can be represented in various ways, including by a formula, a graph, or a table of values. For instance, the function that squares a number can be represented by the formula f(x) = x^2. This means that for any input x, the output is x multiplied by itself. The graph of this function is a parabola, and a table of values would show pairs of numbers like (1, 1), (2, 4), and (3, 9).

The concept of a function is fundamental to many areas of mathematics and science. It is used to describe relationships between variables, model physical phenomena, and solve complex problems. In computer programming, functions are also a core concept, allowing for the creation of reusable blocks of code that perform specific tasks. These programming functions are analogous to mathematical functions in that they take inputs (arguments) and produce outputs (return values). Understanding functions is crucial for comprehending calculus, abstract algebra, and numerous other advanced mathematical disciplines.
