[pstricks] Can I get a x-coordinate from a point anyhow?

Hello everyone,
I ask for your help for the following problem: I want to plot two
function f,g on [xmin,xmax] which have an intersection point S=(s1,s2).
The tricky thing about it is, that I want to plot the functions
differently on [xmin,s1] and [s1,xmax], for example red and blue.
As I only know S, but not the coordinates s1 and s2 themselves, I wonder
how I can achieve that.
Maybe I have to use some more postscript inside?
Any ideas are welcome.
Thanks in advance



\pstInterFF{25 2.71 x neg 0.25 mul exp mul}{10 2.71 x neg 0.1 mul exp
