Quadratic graph lines are U- or Ո-shaped, which is called a parabola. A linear graph can be drawn using only three points. A quadratic graph is a curve, so more points are plotted to support accuracy.

A parabola is a curved line with particular characteristics. Any point on the curve is the same distance from a fixed point and a fixed straight line. The result looks like half of an ellipse or the ...

The minimum point is the minimum y value that the parabola reaches. The maximum point is the maximum y value that the parabola reaches. The symmetry of the parabola is created because each x value is ...

These two paper sheets show drawings of parabolas. One is labeled: 1259 (/) Fig 2. It represents the equation x 2 + 4x + 4 = y. The other is labeled: Sheet 1266 (/) Fig 4. It represnts the equation x ...
