## Main Question or Discussion Point

Hi, I have fitted a graph with a function of the form

[tex]y(x) = a + bx^{-2} + cx^{-4} + dx^{-6}[/tex]

I now need to calculate x for a given y and have no idea how to go about rearranging this function.

I need to find x for a lot of y values, so I was hoping to write something in methematica, but I need to understand how to rearrange it before I can implement it in mathematica.
