Graphing Quadratic Functions Algebra II 3.1

TERMDefinitionEquation Parent Function Quadratic Function Vertex Axis of Symmetry y-intercept Maximum Minimum A set of basic functions used as building blocks for more complicated functions Standard Form where The highest point or lowest point on the graph (depends on if the parabola faces up or down) Vertical Line that goes through the vertex; makes right and left side of parabola symmetrical The point where the graph crosses the y-axis When parabola is flipped downward, the highest point on the graph When parabola is flipped upward, the lowest point on the graph

Example – Graph the Quadratic Equation A. Find the y-intercept B. Find the equation of the axis of symmetry C. Find the coordinates of the vertex D. Create a table of values E. Graph the points y-intercept: 5 (0, 5) Axis of symmetry: Vertex:

Example

Graph the inequality.
