Applying it's definition, the inverse of the function f(x) = 9x + 7 is given by:
\(f^{-1}(x) = \frac{x - 7}{9}\)
How to find the inverse of a function?
Suppose we have a function y = f(x). To find the inverse function, we exchange x and y in the original function, then isolate f.
In this problem, the function is:
y = 9x + 7
Exchanging:
x = 9y + 7
Isolating y:
9y = x - 7
\(y = \frac{x - 7}{9}\)
\(f^{-1}(x) = \frac{x - 7}{9}\)
