Once I plot y = x^y, I notice that it does not pass vertical line, hence not function. i dont understand one thing... it can be rewrite as y = x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x^x... why is it not function?
y = x is function, y = x^x is function, y = x^x^x is function too and so on. why isnt y=x^y function?
i think because to re-write that, you plug the function into itself, which doesnt work

whoever said y = x^y isn't a function?
Well, it doesnt follow the pattern (see my second reply) if the number of exponent is finite, it is function, otherwise its not. why?
@lgbasallote plot it yourself and you can notice it doesnt pass vertical line test
if you try to solve for x y = ylnx y/y = lnx 1 = lnx can you now see why it's not a function?
should have thought of that. thanks
what the ... ?
but seriously...who said it isn't a function?
ln y = ylnx
and...what did i just do?
@lgbasallote well, it isnt, right?
you just proved this.
@hartnn exactly..that's why i'm wondering why qwerties is saying it isn't a function
wait...
@qwerties i manipulated my algebra to make it look like not a function
but if you look carefully there is a fallacy in my solution
well, it doesnt pass vertical test. can you explain it?
if it doesnt pass vertical line test, is it mean it still can be function?
y = x^y according to my math vocabulary is what others call a recursive "function"
