how to find the vertex in a vertex form equation The vertex form of a quadratic function is given by f x a x h 2 k where h k is the vertex of the parabola Remember the vertex is the turning point When written in vertex form h k is the vertex of the parabola and x h is the axis of symmetry
If you re looking at a graph the vertex would be the highest or lowest point on the parabola The easiest way to find the vertex is to use the vertex formula If your equation is in the form ax 2 bx c y you can find the x value of the vertex by using the formula x b 2a To find the vertex of a quadratic function which is the highest or lowest point on its graph I follow these systematic steps Recognize the quadratic equation s formula which is y a x 2 b x c In this formula a b and c represent the coefficients and constant terms of the polynomial respectively
