Compare the domains and ranges of y = sqrt(x-1) and y = sqrt(x+1).
Using a hint is okay. It just tells the trainer to give you a little more review.

extract allowed inputs and outputs from representations.
Hidden until you reveal it.
Representations must show discrete/continuous or restricted/unrestricted differences.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Find each function's allowed inputs.
2. Find possible outputs for those inputs.
3. Compare discrete versus continuous and restricted versus unrestricted behavior.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Comparing equations without domain/range statements.
