Hi MHF, knowing that the quadratic function does not admit inverse, and that a modular function have inverse? if yes, how can i find for example y= |x+2|-|3x+2|.

What is |2|? What is |-2|?

A function is either one-to-one or it is not. I don't know what you mean by "never be". You don't think it is sometimes one-to-one and sometimes not? - Oct 5th 2012, 08:43 AMChipset3600Re: Inverse function
|2|=|-2|=2... The doubt is If there is any modular function that admits inverse?
