The graph input tool Some questions allow you to interact indirectly with a graph by manipulating a corresponding table of entries. In this type of question, you will not be graded on the final appearance of the graph, but rather you will use the graph to help you answer the questions that follow. You can adjust the values in the accompanying table for fields with white backgrounds. Once you have selected a field, you can either enter a new value or adjust the existing value by selecting the arrows (+ to increase and to decrease). You can exit the entry field by hitting Enter (or Return) on your keyboard or by selecting a place elsewhere on the problem. To reset a field to its starting value, select the circular refresh arrow that appears next to the selected field. Experiment with entering different values in the editable fields. Observe what changes take place on the graph itself and also in the uneditable fields in the table. Don't worry about understanding the economics behind the question, just make sure you understand how to manipulate the values on the graph.
