Step 1:
: To find the inverse of a function, we first replace f(x) with y.

This gives us the equation y = 7x.

Step 2:
: Next, we interchange the roles of x and y to find the inverse.

This means we replace y with x and x with y, giving us the equation x = 7y.

Step 3:
: To solve for y, we need to isolate y on one side of the equation.

y = \frac{x}{7}
We can do this by dividing both sides of the equation by 7.

Step 4:
: Finally, to get the inverse function, we replace y with f^- 1(x).

f^{-1}(x) = \frac{x}{7}
This gives us the inverse function:

Final Answer

The inverse of the function f(2$) = 7x is f^- 1(x) = (1 / 7)x.
