A quadratic function can be drawn as a parabola on a graph. Find out how to plot the graph in this Bitesize KS3 maths video.

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

The quadratic formula learned by generations of math students is difficult to remember, but it can be used to solve quadratic equations where y = 0.

The second equation is just a special case of the first, with a = 0.5g, b = v, x = t and c = h. Thus, projectile motion is modeled by a quadratic equation. Graph During the World Pyro Olympics ...
