1. The problem asks for the domain of the function $(q \circ r)(x)$, which means the composition of functions $q$ and $r$. 2. The domain of $(q \circ r)(x)$ is all $x$ values in the domain of $r$ such that $r(x)$ is in the domain of $q$. 3. To find the domain, first identify the domain of $r(x)$. 4. Then find the domain of $q(x)$. 5. Finally, find all $x$ in the domain of $r$ such that $r(x)$ is in the domain of $q$. 6. Without explicit functions $q$ and $r$, the domain of $(q \circ r)(x)$ cannot be precisely determined. 7. If you provide the functions $q$ and $r$, I can find the exact domain in interval notation.
