For this case we must find the inverse of the following function:
![f (x) = 4x + 7](https://tex.z-dn.net/?f=f%20%28x%29%20%3D%204x%20%2B%207)
For it:
Replace f (x) with y:
![y = 4x + 7](https://tex.z-dn.net/?f=y%20%3D%204x%20%2B%207)
We exchange the variables:
![x = 4y + 7](https://tex.z-dn.net/?f=x%20%3D%204y%20%2B%207)
We solve for y:
We subtract 7 on both sides of the equation:
![x-7 = 4y](https://tex.z-dn.net/?f=x-7%20%3D%204y)
We divide between 4 on both sides of the equation:
![y = \frac {x} {4} - \frac {7} {4}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%20%7Bx%7D%20%7B4%7D%20-%20%5Cfrac%20%7B7%7D%20%7B4%7D)
Finally, we change y by
:
![f ^ {- 1} (x) = \frac {x} {4} - \frac {7} {4}](https://tex.z-dn.net/?f=f%20%5E%20%7B-%201%7D%20%28x%29%20%3D%20%5Cfrac%20%7Bx%7D%20%7B4%7D%20-%20%5Cfrac%20%7B7%7D%20%7B4%7D)
ANswer:
![f ^ {- 1} (x) = \frac {x} {4} - \frac {7} {4}](https://tex.z-dn.net/?f=f%20%5E%20%7B-%201%7D%20%28x%29%20%3D%20%5Cfrac%20%7Bx%7D%20%7B4%7D%20-%20%5Cfrac%20%7B7%7D%20%7B4%7D)
