Graphing Module

Enter a function in the f(x) = field and push the Add button. Select a function in the FUNCTIONS menu to toggle its graph status -- a checkmark (✓) designates that a function will be displayed on the graph. When graphing trigonometric functions, use the Angle mode selector on the face of the calculator to toggle between degree and radian modes. Click on the = sign operator in the function line to toggle between equation and inequality (>, <) entry.

The DATA SETS menu allows sets of data points to be created and edited. The REGRESSION menu lists curve types that can be fit to data sets using a least-squares algorithm.

Once a graph has been drawn, click on a function plot to trace its coordinates or change its appearance. Double click the graph background to see zoom options for resizing the graph window. Click on the graph border for title options.
