I would like to know how I could approach the following problem. I am given two functions [itex]y=f(x)[/itex] and [itex]z=g(x)[/itex], and I would like to express the first function as a function of the second one: that is, [tex]y = h(z)[/tex], where

*h*is not necessarily a linear function of

*z*.

One explicit example could be: [tex]y=\frac{x}{a}[/tex] [tex]z=\frac{x}{a+b}[/tex]

where the goal is to find a function

*h*such that [tex]y=h(z)[/tex]
