First we will find the domain:
The domain are all real numbers such that f(x) is defined.
We know that ln(x+2) is defined for (x+2)>0
==> x > -2
Then the domain is `x in (-2,oo).`
`` Now we will find the inverse.
First we switch x and y
==> x = 6- ln(y+2)
Now we will isolate y.
`==gt x - 6 = -ln(y+2) `
`==gt ln(y+2) = 6-x `
`==gt y+2= e^(6-x)`
`` `==gt y= e^((6-x)) - 2`
Then, the inverse function is:
`f^-1 (x)= e^((6-x)) - 2`
To find the inverse function you set y=6-ln(x+2) ->6-y=ln(x+2)
->e^(6-y)=x+2 -> x=e^(6-y)-2
Thus the inverse function is g(x)=e^(6-x)-2
