To determine the transformations from the function \( f(x) = x^2 \) to \( g(x) = -(2x - 2)^2 + 2 \), we can break down the process step-by-step:
1. **Start with \( f(x) = x^2 \)**.
2. **Horizontal Compression**: The term \( 2x \) indicates a horizontal compression by a factor of \( 1/2 \) (since \( \frac{1}{2} \) is the reciprocal of 2). Hence, we compress horizontally.
3. **Translation to the Right**: The term \( -2 \) within \( 2x - 2 \) indicates we are translating the graph to the right by 1 unit (the expression \( 2x - 2 \) can be rewritten to show this).
4. **Reflection Across the x-axis**: The negative sign in front of the squared term indicates that we reflect the graph across the x-axis.
5. **Translation Up**: Finally, the \( +2 \) outside the squared term indicates a vertical translation upward by 2 units.
Now, summarizing the transformations:
- Compressed horizontally
- Translated to the right
- Reflected across the x-axis
- Translated up
So, the correct responses are:
- **compressed horizontally**
- **translated to the right**
- **reflected across the x-axis**
- **translated up**
