Geometry

Question Analysis:
This question requires reflecting a shape over the y-axis.

Key Concept Explanation:
Reflection over y-axis: The x-coordinate changes sign; y stays the same.
Formula: (x, y) → (−x, y).

Step-by-Step Solution:
Original vertex B: (3, 4).
Apply reflection rule: (−3, 4).

Option Analysis:
A) Correct: Follows the reflection rule.
B) Incorrect: Negates y instead of x.
C) Incorrect: Negates both (rotation, n...
