F(x)= 9-x^2, x ≥ 0. f^-1(x)=??

julia-pushkina [17]

$y=9-x^{2},\ x\ge0$

Reverse $x$ and $y$ :
$x=9-y^{2},\ y\ge0$
Solve for $y$ :
$x=9-y^{2}$
$\rightarrow y^{2}=9-x$
$\rightarrow y=\sqrt{9-x}$ since $y\ge0$

I WILL MA FIRST ANSWER BRANILIST The map shows the location of the houses of Dan, Joe, Lee, and the coordinates of the community

emmasim [6.3K]

Lee= (-3,-4)

The only person with coordinates that are both negative is Lee.

"C" is the answer. Lee.
