Quadratic Graph Essentials
- General form: y = ax² + bx + c (where a ≠ 0)
- Shape: Parabola (U-shaped curve)
- a > 0: Opens upward (minimum point)
- a < 0: Opens downward (maximum point)
- Vertex: The turning point (minimum or maximum)
- Axis of symmetry: Vertical line through the vertex

Practice Questions for Quadratic Graphs
The quadratic y = -3x² + 2x - 1 has a negative coefficient of x². What shape does this parabola make?
Explain how the sign of the coefficient a in y = ax² + bx + c determines the shape of the parabola. Your answer should refer to both cases: a > 0 and a < 0.
