The graph of a quadratic function is a parabola. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola. The -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
Hope this helps!!!! :)
