I'm not capable of 'rigorously' defining the problem I have but this is the best I can do.

If I have a set of points that range from $-1$ to $1$ inclusive and I have to transform the data so that it fits onto a range of $0$ to $1$. What's the simple function to do this?

    You want some transformation $\phi$ such that $\phi(-1)=0$ and $\phi(1)=1$ and $\phi$ is linear. So we might think something like $\phi(x)=ax+b$, and you have to find $a,b$ such that $\phi(-1)=...$ etc. So, basically, we have to solve system of two equation. – Cortizol Jun 15 '13 at 21:12

$$ x \mapsto \frac{x+1}{2} $$ ${{{{{{{}}}}}}}$
