Q.

Write the inverse of this function:

$f\left(x\right)=\sqrt{x-8}$

$f^{-1}\left(x\right)=x^2+8$

$f^{-1}\left(x\right)=x+8$

$f^{-1}\left(x\right)=x^2-8$

$f^{-1}\left(x\right)=x-8$

Q.

Write the inverse of this function:

$g\left(x\right)=\frac{2}{x}$

$g^{-1}\left(x\right)=\frac{2}{x}$

$g^{-1}\left(x\right)=2x$

$g^{-1}\left(x\right)=-\frac{2}{x}$

$g^{-1}\left(x\right)=-2x$

Q.

Write the inverse of the function:

$h\left(x\right)=x^2-9$

$h^{-1}\left(x\right)=\pm\sqrt{x+9}$

$h^{-1}\left(x\right)=\sqrt{x+9}$

$h^{-1}\left(x\right)=\pm\sqrt{x-9}$

$h^{-1}\left(x\right)=-\sqrt{x+9}$

Q.

Write the inverse of the function:

$f\left(x\right)=3x-7$

$f^{-1}\left(x\right)=\frac{x+7}{3}$

$f^{-1}\left(x\right)=\frac{x-7}{3}$

$f^{-1}\left(x\right)=3x+7$

$f^{-1}\left(x\right)=3x-7$

Q.

Write the inverse of the function:

$n\left(x\right)=\frac{2x-5}{5}$

$n^{-1}\left(x\right)=\frac{5x+5}{2}$

$n^{-1}\left(x\right)=5x+5$

$n^{-1}\left(x\right)=\frac{5x-5}{2}$

$n^{-1}\left(x\right)=\frac{2x-2}{5}$

Q.

Write the inverse of the function:

$m\left(x\right)=5+x^2$

$m^{-1}\left(x\right)=\pm\sqrt{x-5}$

$m^{-1}\left(x\right)=-\sqrt{x-5}$

$m^{-1}\left(x\right)=\pm\sqrt{x+5}$

$m^{-1}\left(x\right)=\sqrt{x-5}$

Q.

Write the inverse of the function:

$b\left(x\right)=\frac{4}{x}-9$

$b^{-1}\left(x\right)=\frac{4}{x+9}$

$b^{-1}\left(x\right)=\frac{4}{x-9}$

$b^{-1}\left(x\right)=-\frac{4}{x+9}$

$b^{-1}\left(x\right)=4x+36$
