Answer:
2
Step-by-step explanation:
The parent graph is the one used to create a new function by any of the transformations (reflection about an axis, horizontal/vertical shifts, stretches/compressions).
Start with the square root function
[tex]f(x)=\sqrt{x}[/tex]
Multiply by 3 (vertical stretch)
[tex]h(x)=3\sqrt{x}[/tex]
Replace x with x - 2 (shift to right 2 units)
[tex]g(x)=3\sqrt{x-2}[/tex]
