Answer:
2
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

Multiply by 3 (vertical stretch)
![h(x)=3√(x)](https://img.qammunity.org/2022/formulas/mathematics/high-school/taeb9b0hlrd0m87fo6jm074w4vh62893t1.png)
Replace x with x - 2 (shift to right 2 units)
![g(x)=3√(x-2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/q9wela6f5dff31032nn455lm2txm3dijia.png)
