Quadratic Equation Graph

Explore the properties of a quadratic equation graph

A quadratic equation can be written in the form

y = ax² + bx + c where a, b and c are constants and a ≠ 0

The following activity allows you to explore the properties of a quadratic equation graph.
Move the a, b and c slider bars to explore how it affects shape of the graph. Look at

• the effects of changing a.
• the effects of changing b.
• the effects of changing c.
• the effects of a positive value of a.
• the effects of a negative value of a.
• what happens when a = 0?

Graph of Quadratic Function - Drag the sliders to set the values of a (coefficient of x²), b (coefficient of x), or c (constant term) and watch the shape and position of the graph.
