Hi MHF, knowing that the quadratic function does not admit inverse, and that $\displaystyle \left | X\right | = \sqrt[2]{x^{^2}}$ a modular function have inverse? if yes, how can i find for example y= |x+2|-|3x+2|.

Functions can only have inverses if they are one-to-one on their domain. It's pretty obvious that the example you gave is not one-to-one.
