This document discusses how changing the viewing window of a graph on a graphing calculator can transform the graph in different ways. It provides examples of how adjusting the window parameters of x-range, y-range, and scale can: 1) Stretch or shrink the graph to fit different portions of the coordinate plane 2) Make a cubic graph appear nearly horizontal by restricting the x-range drastically 3) Affect whether the shape of a graph drawn by hand matches what the calculator displays So users are advised to properly adjust the window to ensure graphs are accurate and to include important features like labeled axes and intercepts.
