Relflecting the Exponential Function

The green curve is the graph of the function f(x) = ex. The blue line is the graph of the function g(x) x.  Point A is on f, and A' is the reflection of A along the graph of g(x)

1.) Drag point A along f and observe the red trace.
2.) What are the coordinates of the reflection of point A coordinates (a,b)?
3.) What do you think is the equation of the graph traced by A'?
