Codomain = {7,9,10,8,4} The function f is say is one to one, if it takes different elements of A into different elements of B. Now that you are familiar with the IF function's syntax, let's look at some formula examples and learn how to use it in real-life scenarios. A function f is said to be one-to-one (or injective) if f(x 1) = f(x 2) implies x 1 = x 2. Let's take similar examples to check for certain characteristics of strings. A function is a correspondence between a first set, called the domain, and a second set, called the range, such that each member of the domain corresponds to exactly one member of the range.

Excel String (Text) Functions (Examples + Sample Files ... For example, the volume of a cube is given by the function , where is the length of a side. a function takes elements from a set (the domain) and relates them to elements in a set (the codomain ). In all other respects, the two functions are essentially the same. Even after its obtuse purpose (to return back the position of a value within an array), the function clearly has a number of viable uses within Excel.
