### Function

$F(x)=\sqrt(1-x^2)$
$-1\le X \le 0$
now $F^-1(x)=?$

;The result ive got is
$F^-1(x)=F(x)$
$F^-1(x)=-F(x)$

It is supported, but what I tried to say (in other post) is that you can not use equation editor. You have to write them as codes, and most people here use codes, because it takes less time to write codes.

Now look..how nice your equation looks when you use LaTeX.
$f(x)=\frac{1}{\sqrt{1-x^2}}$
where $-1\leq x \leq 0$. now $f^{-1}(x)=?$
