Vertex Steps for graphing quadratics 1 Find the axis of symmetry and vertex a If it is in standard form f x ax bx c use x b 2a b If it is in vertex form f x a x h k the vertex is at h k p q C If it is in factored form f x xp x q use x 2 2 Graph the axis of symmetry and plot the vertex 3 Find two additional points a Make a table b If it is in f x ax bx c form use the y intercept as one of your points If it is in f x x p x q factored form use the zeros as your points C 4 Reflect these points over the axis of symmetry 5 Draw a smooth parabola through the points Graph the function and describe its characteristics Place the axes strategically 1 m x x 4x Axis of symmetry Domain Range Behavior 2 n x x 2x 1 Vertex Axis of symmetry Domain Range Behavior
