Overview of fundamental mathematics functions through interactive graphs

We have all been exposed at some point to the idea of a mathematical function. Most of the time, this concept may remain in the mind as uniquely connected to algebra or even just to some esoteric formulas. We are going to make a small tour of some fundamental functions and try to express them out of the abstract world using interactive graphs.
Maths use madeup rules to create models and relationships, using graph models will help to understand:
 What relationship does a model represent?
 What realworld items share a relationship?
 Does a relationship make sense to us?
For those who can naturally express functions in both the algebraic and geometric world, we hope giving you a refresh from old mathematical memories.
