The axis of symmetry for a parabola is the line that divides it into two symmetric halves. It goes through the vertex of the parabola. In this case, the vertex is located at the point (4, 0).

Since the vertex's x-coordinate is 4, this indicates that the axis of symmetry is a vertical line at this x-coordinate. Therefore, the equation of the axis of symmetry is:

x = 4...
