The axis of symmetry line passes through the vertex of a parabola. It is a vertical line that divides the parabola into two symmetric halves. The vertex is the highest or lowest point on the parabola, depending on whether it opens upward or downward.

The equation of the axis of symmetry is x = h, where h represents the x-coordinate of the vertex. This line is a central lin...
