What this Graphing Parabolas and Key Features quiz checks
- The parabola opens up if a > 0 and down if a < 0.
- Axis of symmetry in standard form: x = −b2a.
- Vertex form y = a(x − h)² + k has vertex (h, k).
- Factored form y = a(x − p)(x − q) has zeros p and q.
- Completing the square turns standard form into vertex form.
