Explains what a parabola is and the vocabulary used to describe one and gives several examples of parabolas in real life.

The resource discusses quadratic functions. Topics examined are parabolas, the vertex, the axis of symmetry, and standard form.

Works through an example to show how to graph a parabola. Also shows what a positive and negative axis of symmetry looks like.

This reference material introduces the terms and equations related to parabolas in the context of conics. Also, relates concepts to previously-learned material and shows how to 'read' from the 'conics' form of the parabola equation.

Students sketch a complete graph using the indicated type of symmetry. The resource consists of an enlarged printable version of a graph available in PDF format.

An interactive page offering a view of a rotating egg, information on rotational symmetry, and definitions of related topics.

Students use a graphing calculator to explore the relationship between the linear factors of a quadratic function and its zeros. They learn that the x-intercepts and axis of symmetry of a quadratic function can be determined from its...

[Free Registration/Login may be required to access all resource tools.] This lesson covers how to find the x-intercepts, vertex, axis of symmetry, and y-intercept of a parabola.

Detailed math tutorial features notes and examples that investigate the process for graphing parabolas.

The most basic quadratic is y = x2. The general technique for graphing quadratics is the same as for graphing linear equations. The quadratics graph as curvy lines (called "parabolas"), rather than the straight lines generated by linear...

In this activity you can learn the geometric and algebraic meaning of the symmetry about any point and any vertical axis.
