Finding the intersect of two curves

Hello there.

I was wondering if there is any way to find the intersection of two curves
without knowing the equation of one of them.

For example, I have the following curves:

ImplicitPlot[function[x,y] == constant, {x, xmin, xmax}, {y, ymin, ymax}]

function[x] == constant


The curve generated by Implicit Plot does not have an explicit equation.  Is
it still possible to find the point where these two curves intersect?

Any help would be greatly appreciated.

Sincerely,

Catherine Neish
