# How to find the vertex of a parabola    The standard and vertex form equation of a parabola and how the equation relates to the graph of a parabola. How to Find the Vertex of a Quadratic Equation. The vertex of a quadratic equation or parabola is the highest or lowest point of that equation. It lies on the plane of symmetry of the entire parabola as well; whatever lies on the left of. Contents: This article covers the vertex form of a parabola, how to find the vertex of a parabola and the intercepts. Please do attempt the QUIZ at the end of the article to ensure a complete understanding of the topic. Vertex of a Parabola: The vertex of a parabola is the high point or low point of the graph. The method you use to find the vertex will depend on the form in which the function is given. You will want to use one strategy when the function is given in vertex form. The general form of a quadratic is y = ax 2 + bx + c. For graphing, the leading coefficient a indicates how fat or how skinny the parabola will be. The Vertex of a Parabola The vertex of a parabola is the point where the parabola crosses its axis of symmetry. If the coefficient of the x 2 term is positive, the vertex will be the lowest point on the graph, the point at the bottom of the “ U ”-shape. In the real world, parabolas describe the path of any thrown, kicked or fired object. They're also the shape used for satellite dishes, reflectors and the like, because they concentrate all rays that enter them into a single point inside the bell of the parabola, called the focus. In mathematical terms, a parabola. Vertex of a parabola, explained with pictures and examples and formulas.
