Answer 1

To determine the sequence of transformations that maps ΔABC to ΔA"B"C", we need to analyze the transformation steps.

1. Reflect over the x-axis: This transformation changes the coordinates from \((x, y)\) to \((x, -y)\).

2. Translate downward by 4 units: After reflecting, we would move the points down by 4 units. This is achieved by changing the y-coordinate, resulting in \((x, -y) \to (x, -y - 4)\).

Therefore, the composition of these transformations is:

1. Reflection: \((x, y) \to (x, -y)\)
2. Translation: \((x, -y) \to (x, -y - 4)\)

Combining these two transformations can be written as:

\[ (x, y) \to (x, -y) \to (x, -y - 4) \]

Therefore, the final transformation that maps ΔABC to ΔA"B"C" is:

\[ (x, y) \to (x, -y - 4) \]

Hence, the correct answer is:

\((x,y) \to (x, -y - 4)\).
