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