Best ResponseYou've already chosen the best response.0Once 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?

Best ResponseYou've already chosen the best response.0y = x is function, y = x^x is function, y = x^x^x is function too and so on. why isnt y=x^y function?

Best ResponseYou've already chosen the best response.0i think because to rewrite that, you plug the function into itself, which doesnt work

Best ResponseYou've already chosen the best response.1whoever said y = x^y isn't a function?

Best ResponseYou've already chosen the best response.0Well, it doesnt follow the pattern (see my second reply) if the number of exponent is finite, it is function, otherwise its not. why?

Best ResponseYou've already chosen the best response.0@lgbasallote plot it yourself and you can notice it doesnt pass vertical line test

Best ResponseYou've already chosen the best response.1if you try to solve for x y = ylnx y/y = lnx 1 = lnx can you now see why it's not a function?

Best ResponseYou've already chosen the best response.1but seriously...who said it isn't a function?

Best ResponseYou've already chosen the best response.0@lgbasallote well, it isnt, right?

Best ResponseYou've already chosen the best response.1@hartnn exactly..that's why i'm wondering why qwerties is saying it isn't a function

Best ResponseYou've already chosen the best response.1@qwerties i manipulated my algebra to make it look like not a function

Best ResponseYou've already chosen the best response.1but if you look carefully there is a fallacy in my solution

Best ResponseYou've already chosen the best response.0well, it doesnt pass vertical test. can you explain it?

Best ResponseYou've already chosen the best response.0if it doesnt pass vertical line test, is it mean it still can be function?

Best ResponseYou've already chosen the best response.1y = x^y according to my math vocabulary is what others call a recursive "function"
