3.2 Graph of Quadratic Function

3.2 The Graph of Quadratic Function

  1. The graph of quadratic function is parabola.
  2. When the coefficient of x2 is positive the graph is a parabola with U shape.
  3. When the coefficient of x2 is negative the graph is a parabola with ∩ shape.

Axis of Symmetry

The axis of symmetry is a vertical line passing through the maximum or minimum point of the parabola.
