Answer:
![\frac{x-8}{7}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-8%7D%7B7%7D)
Step-by-step explanation:
A way to find the inverse function is to swap the x and y (f(x)) in the equation.
![y = 7x + 8\\x = 7y + 8\\x-8 = 7y\\y = \frac{x-8}{7}](https://tex.z-dn.net/?f=y%20%3D%207x%20%2B%208%5C%5Cx%20%3D%207y%20%2B%208%5C%5Cx-8%20%3D%207y%5C%5Cy%20%3D%20%5Cfrac%7Bx-8%7D%7B7%7D)
We can check that it is an inverse function by using a property of inverse functions:
![f(g(x)) = x](https://tex.z-dn.net/?f=f%28g%28x%29%29%20%3D%20x)
If we plug in the f(x) function into the variable x of the inverse function, we should end up with x
![y = \frac{(7x + 8) - 8}{7}\\y = \frac{7x}{7} \\y = x\\](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B%287x%20%2B%208%29%20-%208%7D%7B7%7D%5C%5Cy%20%3D%20%5Cfrac%7B7x%7D%7B7%7D%20%5C%5Cy%20%3D%20x%5C%5C)
It checks out!
