Hello there!

In my work, I will have to convert functions. My English is crap, so I will just show you what I mean.

If I have a function:

y = x + 1 i can convert it to look like this: x = y - 1. I would like to do the same for:

y = x^3 + x^2 + x + 1

or this:

y = x^4 + x^3 + x^2 + x + 1

or this:

y = x^5 + x^4 + x^3 + x^2 + x + 1

How is that done?

Thank you.

Kind regards,

Marius
