```p = h(x,y)
q = r(x,y)
Are given inverse functions.  Non linear might means they contain any
expressions that are not linear.  What are they?

ExpandAll expands.

As far as h and r I don't know that simple substitution to solve for
f^-1 will suffice being that you said it's a series.

Also:  once you substitute values for points in the equation there is
no opportunity to find inverse symbolicly.

If you get really stuck in the symbolism of inversing you can instead
map values of f, g, p, q in a table and reverse map the Domain Range
table.
