• D. $x=4$

Answer: (A)

Verified step by step guidance

1. Identify the vertex of the parabola on the graph. The vertex is the point where the parabola changes direction, and it is located at the lowest or highest point of the curve.
2. Observe the graph and locate the vertex. In this graph, the vertex appears to be at the point (3, 0).
3. Understand that the axis of symmetry of a parabola is a vertical line that passes through the vertex. This line divides the parabola into two mirror-image halves.
4. Since the vertex is at (3, 0), the axis of symmetry is the vertical line that passes through x = 3.
5. Conclude that the axis of symmetry for this parabola is x = 3, as it is the line that passes through the vertex and divides the parabola symmetrically.
