how to find the vertex using vertex form A quadratic equation is an equation of the form y ax 2 bx c where a b and c are constants The graph of a quadratic equation is in the shape of a parabola which can either face up
For standard form y Ax 2 Bx C Look at the coefficient of the x 2 term If A is positive the parabola opens up If A is negative then the parabola opens down For Vertex Form y a x h 2 k The sign of a determines the direction of the parabola If a is positive the parabola opens up 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
