Vertical Axis of Symmetry: Vertical axis of symmetry: Vertex: (opens upwards) or Focus: (opens downwards) Directrix: (h, k) = vertex of parabola Horizontal Axis of Symmetry: Vertical Axis of Symmetry: Horizontal axis of symmetry: Vertex: (opens right) or Horizontal Axis of Symmetry: Focus: (opens left) Directrix: Parabola General Form: Projectile Motion: where where feet or meters If B ≠ 0, then coordinate system: General Form: New = (x’, y’), Old = (x, y) where A and L have the same sign rotates through angle from x-axis Nose Cone
