yes

Answer 4

Ok.
Do you know how to get the inverse of a function?

Answer 5

\[y = x^2 + 9\]
\[x = y^2 + 9\]

Answer 6

To get the inverse of any function f(x) [ just make sure that it passes the horizontal line test] follow the steps:

- Solve for x, i.e separate x in one side and the other terms in the other side, included f(x).
- Swap x and f(x).
- The result is the inverse of the original function \(f^{-1}(x)\).
