There are two different formulas that you can use to find the axis of symmetry. One formula works when the parabola's equation is invertex formand the other works when the parabola's equation is instandard form. Standard Form If your equation is inthe standard formy=ax2+bx+cy=ax2+bx+...
Axis of Symmetry of a ParabolaThe line passing through the focus and vertex of a parabola. The axis of symmetry is perpendicular to the directrix.Example: This is a graph of the parabola with all its major features labeled: axis of symmetry, focus, vertex, and directrix....
