QuestionCheck if $f(x)=5x+9$ and $g(x)=\frac{x-9}{5}$ are inverse functions by finding $(f \circ g)(x)$ and $(g \circ f)(x)$.

Studdy Solution
Since both $(f \circ g)(x) = x$ and $(g \circ f)(x) = x$, we can conclude that $f(x)$ and $g(x)$ are inverse functions.
Thus, $g(x)$ is the inverse function of $f(x)$.
