Intersections of two 'curves'

I have one last ‘problem’ I wish to solve, before I publish my ‘class’ on depth of field in photography.

The problem is, I can’t work out how to get demos to calculate the intersection coordinates of two ‘curves’, ie two functions.

I know I can click on the points to get the coordinates, but I want demos to ‘solve’ the intersection and give me the {x,y} coordinates at the intersection(s).

Does anyone know if there is a way to do this?

I don’t think there’s any (easy) way to get Desmos to do it for you. If you give the two functions, someone could probably give the workaround. You’re basically finding the zeros of f(x)-g(x), but desmos doesn’t have a way of creating a list of solutions. If there’s just one solution you can do it, but not multiple solutions.

Daniel thanks, that is what I concluded after trying f(x)-g(x) route.

Thanks for picking up.
