To identify the sequence of transformations that will carry triangle \( \Delta ABC \) to \( \Delta A"B"C" \), we can analyze the transformations involved.
The transformations involve a reflection and a translation. The correct transformation sequence is:
- Reflect over the x-axis: This will change \( (x, y) \) to \( (x, -y) \).
- Translate upwards: Depending on the final position, if we need to move up, it could be represented as \( (x, -y) \) to \( (x, -y + k) \) for some \( k \).
From your options, the transformation that matches the description of reflecting across the x-axis and then translating is:
- Translation by 4 units upwards after reflection: \( (x, y) \rightarrow (x, -y) \) to start, then shift up by 4 units to get \( (x, -y + 4) \).
Therefore, the correct composition transformation mapping is:
\[ (x, y) \rightarrow (x, -y + 4) \]
This indicates that \( \Delta ABC \) is first reflected over the x-axis and then moved up by 4 units.
