WebThe vertex (h, k) is located at h = – b 2a, k = f(h) = f(− b 2a) How To Given a graph of a quadratic function, write the equation of the function in general form. Identify the horizontal shift of the parabola; this value is h. Identify the vertical shift of the parabola; this value is k. WebThe vertex is apparent (h, k) in the vertex form. Parabolas can model many real life situations, such as the height above ground of an object traveling upward for some period of time. The vertex of the parabola can provide us with information, for example, about the maximum height reachable by the upward traveling object.
