QuestionFind $(f \circ g)(x)$ and its domain for $f(x)=\frac{5}{x^{2}+36}$ and $g(x)=\sqrt{4+x}$.

Studdy Solution
implify the denominator.
$$(f \circ g)(x) = \frac{5}{40+x}$$So, the composition of the functions $f$ and $g$ is $(f \circ g)(x) = \frac{5}{40+x}$.We will find the domain in the next part.
