Quadratic equations are basic to algebra and are the math behind parabolas, projectiles, satellite dishes and the golden ratio.

How to draw a quadratic graph from a table of values 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 ...

How to Graph a Parabola in Word. 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 ...

In this 3-part activity, students use paper-folding and an interactive computer sketch to develop the equation of a parabola given the focus and directrix.

A parabola is a symmetrical curve that can describe the path of a projectile, like a thrown football, or the curve of a suspension bridge. Parabolas are defined with variations on the equation y = x2.
