The vertex of a quadratic function is the absolute minimum (in the case of an upward-opening parabola) or maximum (in the case of a downward-opening parabola) of that function. It is the point ...

Learn how to find the X-intercept(s) and Vertex of a parabola, and see examples that walk through sample problems step-by-step for you to improve your math knowledge and skills.

Learn how to find the focus and directrix of a parabola in vertex form, and see examples that walk through sample problems step-by-step for you to improve your math knowledge and skills.

Learn how to find the vertex, intercepts, and axis of symmetry from the graph of a parabola, and see examples that walk through sample problems step-by-step for you to improve your math knowledge ...

How do you find the axis of symmetry of a parabola? As explained previously, in this lesson, the axis of symmetry is a vertical line that passes through the vertex of the parabola.

Learn how to find the equation of a parabola with its focus and directrix in this bite-sized video lesson. Enhance your geometry skills by taking a quiz for practice.

The x-intercepts and the y-intercept, along with the vertex, are helpful to sketch the graph of a parabola. A quadratic function y = a x 2 + b x + c has vertex V (b 2 a, b 2 4 a c 4 a).

A parabola is the set of all points which are the same distance from the focus and the directrix. The directrix also provides whether a parabola opens up/down or left/right.
