GraphEasyRect allows graphing f(x) on cartesian plane. It shows points of discontinuity encircled on the graph. Viewport may be moved any where on the cartesian plane. Graphs may be printed. Data values for function my be displayed and/or copy pasted into applications such as Excel. Graph view may be zoomed in or out by adjusting minimum and maximum values for x-axis and y-axis. From simple to complicated function, it draws them all.
