In the inverse functions when you need to find if these two functions are inverse to each other or not you composition…if i did f•g and the answer was x i don’t need to dog•f right?

Sorry for bad english

Sorta. There exist left and right inverses.

Consider $f(x)=x^2$ and $g(x)=-\sqrt{x}$. What do you get when calculating $(g\circ f)(x)$ and $(f\circ g)(x)$?
