What are the key features of a parabola?

Back

The key features of a parabola include the vertex, axis of symmetry, direction of opening (upward or downward), and intercepts.

Front

What is the vertex of a parabola?

Back

The vertex of a parabola is the highest or lowest point on the graph, depending on whether it opens upward or downward.

How do you find the axis of symmetry of a parabola?

Back

The axis of symmetry can be found using the formula x = -b/(2a) from the quadratic equation in standard form.

What is the range of a quadratic function that opens upward?

Back

The range is all real numbers greater than or equal to the y-coordinate of the vertex.
