Question

What is the inverse of the fuction f(x)=19/x

Answer 1

Answer:

$f^-^{1} (x)=\frac{19}{x}$

Step-by-step explanation:

To find the inverse of this function, switch the variables like this:

$\frac{19}{x}\\\\x=\frac{19}{y}$

Then, solve for y, like this:

$y= \frac{19}{x}$

Replace y with $f^-^{1} (x)$.

$f^-^{1} (x)=\frac{19}{x}$
