CHAPTER 6. GRAPHING EQUATIONS/FUNCTIONS
The problem with this window is that you cannot see part of the graph. What you need to do
is to adjust the viewing window to go down further on the vertical axis. Go back to the
WIN-
DOW
screen by pressing
. Scroll down to
ymin
, and change it to
−
20
.
Graph the function using the new window settings,
, and you will see the entire graph.
Notes:
i. With the new dimensions on the vertical axis, the tick marks are very close. You could adjust
this by changing the
yscl
setting in the
WINDOW
screen.
ii. These new viewing window settings have been saved and will used the next time you graph
a function, unless you remember to change them.
