How to Find the Vertex of a Parabola Equation
Someone new to algebra may find it difficult to find the vertex of a parabola equation. The vertex is the maximum or minimum point of a parabola defined by a quadratic equation. There are two main forms of a quadratic from which you must ca... Read More »

How to Find the Focus of a Parabola in Vertex Form
A parabola's focus helps to define its curve. A parabola's focus, a single point with coordinates that depend on the vertex, lies inside the parabola's curve. The focus works in tandem with the parabola's directrix, a straight line on the o... Read More »

How to find the vertex of a parabola?
The vertex is halfway between the focus and the directrix. Both vertex and focus are on axis of symmetry. Make a little drawing to see what is happening. vertex in this case is (1, 1/2) Don't forget, focus above vertex means parab opens up,... Read More »
