u To draw and analyze the asymptotes [G-SLV]-[ASYM]
Example To draw the asymptotes for the hyperbola
Use the following V-Window settings.
Xmin = –6.3, Xmax = 6.3, Xscale = 1
Ymin = –5, Ymax = 5, Yscale = 1

# Certain V-Window parameters can produce
errors in values produced as graph analysis
results.
# 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.
