Answer:
Explanation:
When a point is reflected in the y-axis, its x-coordinate is negated while the y-coordinate remains unchanged. In this case, the vertex of the parabola is given as (2, 5). After reflecting it in the y-axis, the x-coordinate, which is 2, becomes -2, while the y-coordinate, which is 5, remains the same.
Therefore, the image of the vertex after the reflection is (-2, 5).
