thats just how exponential functions work famalam, e shows up everywhere

nice non-explanation

take the log base x of both sides, then apply the change of base formula to rewrite your equation in terms of natural logarithms and see what you get.

I wish I could find an equation to that weird curve there but unfortunately I can't.

Anyways, there is a simple explanation.

Instead of working with two functions lets deal with constants. Set x=2 and get
2^y = y^2

There is the trivial solution y=2 but notice that y=4 also works. Do the same analysis now with e.

e^x = x^e

The only solution there is x=e so there is no magical second solution which, if you notice, is what defines that second curve.

But whyyyyyy

Do you mean Lambert function?

But why isn't there. It's been proven that (2,4) and (4,2) are the only whole number solutions if x != y. But why is it that every single positive number has two other positive numbers that when raised to eachother's power will equal the first number. Why is e the exception?

x^y = y^x is the same as e ^ y ln(x) = e ^ x ln(y)
