Problem 86 of 7
Interpret increasing and decreasing intervals for advanced function y=-sqrt(x)+4.
Using a hint is okay. It just tells the trainer to give you a little more review.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify domain intervals separated by endpoints, asymptotes, or extrema.
2. Read whether outputs rise or fall as x increases on each interval.
3. Interpret the behavior in context if units are given.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying a function increases across a discontinuity as one uninterrupted interval.
