How to find the inverse function of the function f(x) = 3/x?

Edwin Simmons

Explanation:
$f\left(x\right)=\frac{3}{x}$
$y=\frac{3}{x}$
Change the variables and find for $y$.
$x=\frac{3}{y}$
$xy=3$
$y=\frac{3}{x}$
${f}^{-1}\left(x\right)=\frac{3}{x}$
Hence, the inverse of $f\left(x\right)=\frac{3}{x}$ is itself.
