Help with this question, it is one question with 3 parts.

Answer 1

The given function is ,

`f(x)=(x+12)/(x-6)`

The inverse of the function is ,

`\begin{gathered} y=(x+12)/(x-6) \\ x=(y+12)/(y-6) \\ y=(6(x+2))/(x-1) \\ f^(-1)(x)=(6x+12)/(x-1) \end{gathered}`

for x ,

`x<1\text{ and x>1 .}`

if x= 1 the function will be undefined.

thus,

`x\\e1`
