Geometry Graphing Quadratics in Standard Form with Tables Examples Convert each quadratic into vertex form. Identify the vertex and Axis of Symmetry for each problem. Then graph the quadratic equations by making a table of values. Show work! 1. y = x 2 – 4x + 9 : Vertex Form: _____________ Vertex: ________ A. O S.: ________ 2. y = -x 2 – 12x - 39 Vertex Form: ______________ Vertex: __________ A. O S.: ________ 3.y = 2x 2 + 12x + 11 Vertex Form: ______________ Vertex: __________ A. O S.: ________ X Y X Y X Y
