Here we have , f(x) = y= 7x-6

To find the inverse function of the given function, we need to follow some steps, which are:

First we need to switch x and y, that is

x= 7y-6

Next step is to solve for y, and for that, we need to add 6 to both sides

x+6=7y

Dividing both sides by 7, that is

[tex] y = \frac{x+6}{7} [/tex]

Therefore,

[tex] f^{-1}(x)= \frac{x+6}{7} [/tex]
