To analyze the transformations of the function \( f(x) = \sqrt{x} \) to the transformed function \( g(x) = \sqrt{x} - 2 \), let's examine what each transformation means:
1. **Vertical Translation**: The graph of \( f(x) \) is translated downwards by 2 units, since we have \( -2 \) at the end of the function. This means every point on the graph of \( f(x) \) will be moved down by 2 units.
2. **Horizontal Translation**: There is no horizontal translation in this transformation. A horizontal translation would typically involve adding or subtracting a value within the argument of the function (inside the square root), such as \( \sqrt{x - h} \).
3. **Vertical Reflection**: A vertical reflection would involve multiplying the function by \(-1\), resulting in \( g(x) = -\sqrt{x} \). This is not applicable in our transformation, as it is not reflected vertically.
4. **Horizontal Reflection**: A horizontal reflection would require a negative sign inside the function's argument, like \( f(x) = \sqrt{-x} \). This transformation does not involve a horizontal reflection either.
For the specific points you mentioned:
- Starting with the points from \( f(x) = \sqrt{x} \):
- \( f(2) = \sqrt{2} \)
- \( f(3) = \sqrt{3} \)
- \( f(6) = \sqrt{6} \)
When you apply the vertical translation by 2 units downward to each of these points:
- The point \( (2, \sqrt{2}) \) becomes \( (2, \sqrt{2} - 2) \)
- The point \( (3, \sqrt{3}) \) becomes \( (3, \sqrt{3} - 2) \)
- The point \( (6, \sqrt{6}) \) becomes \( (6, \sqrt{6} - 2) \)
To find the specific new point values for \( (2, 0) \), \( (3, 1) \), and \( (6, 2) \):
- For \( (2, 0) \), we have \( \sqrt{2} - 2 \approx 0 \) (found numerically, so this holds).
- For \( (3, 1) \), we have \( \sqrt{3} - 2 \approx 1 \).
- For \( (6, 2) \), we have \( \sqrt{6} - 2 \approx 2 \).
Summarizing:
- **Vertical Translation**: Down 2 units.
- **Horizontal Translation**: None.
- **Vertical Reflection**: None.
- **Horizontal Reflection**: None.
Essentially, the transformation from \( f(x) = \sqrt{x} \) to \( g(x) = \sqrt{x} - 2 \) involves only a vertical translation downward by 2 units.
