3.06 Focus on Quadratics
This task requires you to create a graph. You have several options:
● Use the Word tools;
● Draw the graph by hand, then photograph or scan your graph; or
● Use the GeoGebra linked on the Task page of the lesson to create the graph; then, insert a
screenshot of the graph into this task.
