	If I constrained a bezier curve to conform to a function (as in
"every x value has one and only one y value"), and plotted it out via a 
curveto operator, is there any way that I could find out what the y value
for a point along the curve would be for any x value?  Either the relevant
equations for a Bezier curve or some ps code to trace it would be very  
helpful.

	Thanks.
