Question

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

Answer 1

`f^-^(1) (x)=(19)/(x)`

Explanation:

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

`(19)/(x)\\\\x=(19)/(y) \\`

Then, solve for y, like this:

`y= (19)/(x) \\`

Replace y with
`f^-^(1) (x)`.

`f^-^(1) (x)=(19)/(x)\\`
