The situation is as follows:

  • I performed necessary measurements and used them to create two graphs.

  • I used polynomial regression to find the point of intersection.

What I know:

  • precision of instruments (absolute error of X and Y values of the points belonging to the graphs).

  • polynomial regression equations and coefficients of determination.

What I need to find out:

  • uncertainty of X and Y values of the intersection point.

In case something sounds unclear (English obviously isn't my native language) - I basically need to do something similar to this (but with polynomial regression)

The question is: what methods should be used to accomplish it?
