The graph of every quadratic function shares several defining characteristics that are helpful for sketching and analysis:
-intercept , the point where the graph crosses the vertical axis quadratic functions pdf download
-axis. These are also called zeros or solutions to the equation : This value tells you how many roots the function has: : Two distinct real roots. : One real root (the vertex touches the : No real roots (the graph never touches the Four Methods to Solve Quadratic Equations The graph of every quadratic function shares several
