Analyzing Quadratic Graphs Worksheet Answer Key Write the Quadratic Functions This set of printable worksheets requires high school students to write the quadratic function using the information provided in the graph If the x intercepts are known from the graph apply intercept form to find the quadratic function If the vertex and a point on the parabola are known apply vertex form
Option 1 If it factors find the zeros The middle of the two factors is the axis of symmetry b Option 2 If it doesn t factor find the axis of symmetry with x 2 a Plug the x value into the original equation to find the y value of the vertex The y intercept is at 0 c 13 y x2 2x 3 1 Write the equation of a quadratic function 2 Write the equation of the axis of symmetry 3 For each quadratic equation identify a b and c State whether the vertex point will be a maximum point or a minimum point y 2x x Axis of symmetry For each quadratic equation find the axis of symmetry 4 y x2 4x 3 5
