qwerties Group TitleBest ResponseYou've already chosen the best response.0
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 rewrite 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?

@hartnn exactly..that's why i'm wondering why qwerties is saying it isn't a function

@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?

qwerties Group TitleBest ResponseYou've already chosen the best response.0
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"
