Question Analysis
This question tests the student's understanding of the axis of symmetry of a parabola and how it relates to the vertex. The axis of symmetry is a vertical line passing through the vertex, and it is equidistant from any two symmetric points on the parabola.

Key Concept Explanation
The axis of symmetry of a parabola is a vertical line that passes through the vertex. For a parabola that is symmetric about the y-axis, the x-coordinate of the vertex (h) is the midpoint of the x-coordinates of any two symmetric points. The formula for the axis of symmetry is , where is the x-coordinate of the vertex.
