The condition for two functions, $f(x)$ and $g(x)$, to be inverses of each other is that $f(g(x)) = x$ and $g(f(x)) = x$, not $f(x) \cdot g(x) = x$.

f(x)=x and g(x)=xf ( x ) = \sqrt { x } \text { and } g ( x ) = \sqrt { x }f(x)=x​ and g(x)=x​

$f ( x ) = \sqrt { x } \text { and } g ( x ) = \sqrt { x }$
