Graphing Parabolas

Start with the shape

The Parabolas mind maps offer several starting points. One defines a parabola using a fixed point called the focus and a fixed line called the directrix. Another introduces the vertex, the axis of symmetry and the equation of a parabola. Since several maps share the title Parabolas, look at their contents to find the one that fits what you want to study.

For a shorter review of graph features, the Quadratics mind map brings together the vertex and axis of symmetry. It also includes the expression x = -b/2a for the axis of symmetry.

Move from maps to practice

After looking over the key terms, use the Quadratic Graphs flashcards to work through questions about the vertex, the axis of symmetry and the first step in creating a quadratic graph. The notes on quadratic functions cover graphing functions in the form y = ax² + bx + c and introduce zeros of a function.

The quiz Graphs of Quadratic Functions offers a way to practice after studying the maps. Pre-Test on Parabolas is another option if you want to begin with a quiz. You can then return to a map or the flashcards to review terms that need more attention.

Place the topic in the unit

Graphing Parabolas is a section of Quadratic Equations and Functions in Mathematics. The resources connect the shape of a parabola with features of quadratic graphs, including the vertex, symmetry and equations. Using a map alongside a quiz gives you a way to move between those descriptions and practice.

Choose a resource that matches your starting point and explore the section at your own pace.
