### Introduction to functions

Introduction to functions mc-TY-introfns-2009-1 A function is a rule which operates on one number to give another number However, not every rule describes a valid function This unit explains how to see whether a given rule describes a valid function, and introduces some of the mathematical terms associated with functions.

Live Chat### Injective function

In mathematics, an injective function or injection or one-to-one function is a function that preserves distinctness: it never maps distinct elements of its domain to the same element of its codomain In other words, every element of the function's codomain is the image of at most one element of its domain.
