QuestionFind the inverse of the function $f(x)=9+\sqrt{4x-9}$ for $x \geq 9$.

Studdy Solution
Finally, we denote $y$ as $f^{-1}(x)$ to indicate that $y$ is the inverse of the function $f(x)$$$f^{-1}(x) = \frac{x^2 -18x +90}{4}$$So, the inverse of the function $f(x)=+\sqrt{4x-}$ is $f^{-1}(x) = \frac{x^2 -18x +90}{4}$ for $x \geq$.
