Demonstration of Graphing Tool is a useful tool that can graph points from tables and lines from equations.  The examples below provide basic instructions for using the program.

Go to:

Graphing Equations

To graph an equation, select “\(f(x)\) expression” from the “+” drop-down menu (shown in Figure 1) and type in the equation on the first line in the left panel.

Figure 1

To graph multiple equations, press “Enter” after typing each equation, or use the “+” from the drop-down menu, and select “\(f(x)\) expression” for each new equation. Figure 2 shows shows multiple graphed equations.

Graphing Tables

To graph a table, select “table” from the “+” drop-down menu (shown in Figure 3), and enter \(x\)- and \(y\)-values to create ordered pairs.

Figure 3

To graph multiple tables, press “Enter” after typing each table, or use the “+” from the drop-down menu and select “table” for each new table. Figure 4 shows multiple tables and their associated plotted points.

Graphing Tables with Graphs

To graph an equation with its points, select “table” from the “+” drop-down menu, and then select “\(f(x)\) expression” from the same menu.  Type in the table values and the equation (shown in figure Figure 5).
