Full solution stays hidden until you ask for it.
1. Check that both endpoints are in the radical domain.
2. Evaluate the function at each endpoint.
3. Divide output change by input change.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Intervals outside an even-root domain.
