Answer: x
6
Explanation
The inverse function is f^-1(x)=1/x-4+6 and the domain is x
6
Express f(x) as y
Swap the positions of x and y
Add 6 to both sides
Multiply both sides by y-4
Divide both sides by x + 6
Add 4 to both sides
Rewrite as: f-1(x)=1/x+6-4
Hence, the inverse function is 4 and the domain is x
