Explanation:
![f(x)=x+4\\y=x+4\\](https://tex.z-dn.net/?f=f%28x%29%3Dx%2B4%5C%5Cy%3Dx%2B4%5C%5C)
We first replace f(x) with y.
We then switch x and y.
![x=y+4](https://tex.z-dn.net/?f=x%3Dy%2B4)
We then find y in terms of x in our new equation.
![y=x-4](https://tex.z-dn.net/?f=y%3Dx-4)
We then replace y with
