Getting cartesian values from Bezier curve question

Hello Wise Ones

I am considering adding a control to allow users to use a Bezier Path to edit a set of values that change over time. The essentials are a timeline with values determined by keyframes which will be represented by Bezier nodes.

My question is, is there a simple way to derive the y value of a bezier line segment given an x coordinate. Assume that there is no circumstance where more than one y value might exist for a given x value. I don't see anything in the NSBezierPath documentation that indicates that this is supported.

For the purposes I will be putting this to, a close approximation - eg 2% error - would suffice.

Anyone?
