For the function defined by f(x)=2-x^2, 0 less than or equal to x, use a sketch to help find a formula for f^-1(x). Gave this one my best shot but I need some help with this one. my answer is: f^-1(x)= squrt2-x, x less than or equal to 2.

$\displaystyle y=2-x^2$ for $\displaystyle x\geq 0 $
It inverse (interchange x and y),
$\displaystyle x=2-y^2$
Thus,
$\displaystyle x-2=-y^2$
Thus,
$\displaystyle 2-x=y^2$
Thus,
$\displaystyle y=\sqrt{2-x}$
Below is the graph,
(red is the original function
gree in the inverse,
balck is the identity function showing the symettry)

Thus, how can that possibly be a trojan! If it claims to be one. Just click it (we have a policy here on MHF that more malware is allowed).
