Answer:
[tex]f^-^{1} (x)=\frac{19}{x}[/tex]
Step-by-step explanation:
To find the inverse of this function, switch the variables like this:
[tex]\frac{19}{x}\\\\x=\frac{19}{y} \\[/tex]
Then, solve for y, like this:
[tex]y= \frac{19}{x} \\[/tex]
Replace y with [tex]f^-^{1} (x)[/tex].
[tex]f^-^{1} (x)=\frac{19}{x}\\[/tex]
