Answer:
, x>=0
Step-by-step explanation:
![f(x)=(x+6)^2](https://tex.z-dn.net/?f=f%28x%29%3D%28x%2B6%29%5E2)
To find the inverse function , replace f(x) by y
![y=(x+6)^2](https://tex.z-dn.net/?f=y%3D%28x%2B6%29%5E2)
Replace x with y and y with x
![x=(y+6)^2](https://tex.z-dn.net/?f=x%3D%28y%2B6%29%5E2)
Solve the equation for y
take square root on both sides
![+\sqrt{x} =y+6](https://tex.z-dn.net/?f=%2B%5Csqrt%7Bx%7D%20%3Dy%2B6)
Now subtract 6 from both sides
![+\sqrt{x}-6=y](https://tex.z-dn.net/?f=%2B%5Csqrt%7Bx%7D-6%3Dy)
replace y with g(x)
![g(x)=\sqrt{x}-6](https://tex.z-dn.net/?f=g%28x%29%3D%5Csqrt%7Bx%7D-6)
