Assignment Q5.
Introduction
What is a function?
It is like a machine that has an
input and an output.
And the output is related
somehow to the input.
Examples
A Function is Special
But a function has special rules:
It must work for every possible input

And it has only one relationship for
each input value
This can be said in one definition:
