Answer: Graph Y

Step-by-step explanation:

The parent function
y = √(x) is always increasing and it has the left-most endpoint at (0,0). Replacing every x with x-1 will move that point one unit to the right to end up at (1,0)

So going from
y = √(x) to
y = √(x-1) shifts the entire curve 1 unit to the right. What results is shown in graph Y.
