Problem 79 of 7
Interpret the domain and range of root model y=sqrt(x).
Using a hint is okay. It just tells the trainer to give you a little more review.

identify valid inputs/outputs from graph/context.
Hidden until you reveal it.
Identify valid inputs and outputs from graph or context for square-root and cube-root models.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Apply radicand restrictions for even roots.
2. Use graph direction and vertical transformations to determine range.
3. Add any contextual restrictions from the model situation.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Imposing square-root restrictions on cube-root models.
