In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f (x) where x is the input. The general representation of a function is y = f (x).
Basically, the concept of functions gives us a way to name the whole process of evaluating a particular expression, so we can talk about it as a whole. We can compare different functions, discuss their properties, or actually operate on functions to make new functions. It also broadens the concept, because not all functions can be
a function relates inputs to outputs; a function takes elements from a set (the domain) and relates them to elements in a set (the codomain). all the outputs (the actual values related to) are together called the range; a function is a special type of relation where: every element in the domain is included, and

Nov 16, 2022 · Definition of a Function. A function is a relation for which each value from the set the first components of the ordered pairs is associated with exactly one value from the set of second components of the ordered pair. Okay, that is a mouth full. Let’s see if we can figure out just what it means.
Illustrated definition of Function: A special relationship where each input has a single output. It is often written as f(x) where x is the input...
Aug 12, 2023 · Definition: Function. A relation in which each \(x\)-coordinate is matched with only one \(y\)-coordinate is said to describe \(y\) as a function of \(x\).
