Use the following View Window parameters.
Xmin = –6.3 Ymin = –5
Xmax = 6.3 Ymax = 5
Xscale = 1 Yscale = 1

5 (ASYM)
(Draws the asymptotes.)
• Certain View Window parameters can produce errors in graph analysis result
values.
• The message ”Not Found” appears on the display when graph analysis is
unable to produce a result.
• The following can result in inaccurate analysis results or may even make it
impossible to obtain a solution at all.
• When the solution is tangent to the x -axis.
• When the solution is a point of tangency between two graphs.
