Hey guys, I've posted this question so many times and still would like an answer. I am just so confused about why it is shaped like that, and what the curve is!frown Please help me, OK? Thanks!

What I know:

  • I graphed it using \(x^{y}=y^{x}\)
  • One of the equations is y = x
  • The self-intersection point is (e, e)
  • The graph is not a hyperbola, it passes through (2, 4) and (4, 2)

What I want to know:

  • Why is the intersection point (e, e)?
  • What type of graph is this?
  • Why does Desmos have such a hard time saying it has a self-intersection point?
