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

;The result ive got is
\[F^-1(x)=F(x)\]
;but the answer is
\[F^-1(x)=-F(x)\]

please Sollute

Your equations are quite illegible.
Please use latex, its easy (so easy that even I can use it)

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.
Please read the following
viewtopic.php?f=9&t=2
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 $f^{-1}(x)=?$

Please install LaTeX fonts in your PC for better looking equations,
learn how to write equations, and don't forget to read Forum Guide and Rules.
