Each picture shows the graph of a quadratic function. Some functions have real roots, while others have complex roots. Choose the graphs representing quadratic functions with complex roots. If you would like to enlarge the graph or make numbers and letters easier to read, you may click on it to open it in a new window. You may then enlarge that window with your mouse. To further enlarge the image, use your browser’s zoom capabilities. On a PC this is usually ctrl shift + (and zooming out is ctrl -). On an Apple computer this is usually apple shift + (and zooming out is apple -). Select the letters of the graphs where the quadratic function has complex solutions.
