Press to return to the Main Menu and to access the Graph mode
Notice the regression equation copied to Y Y = appears in the Graph mode
as well.
Set the view window by pressing (V-Window). The
circumference must be greater than or equal to 0, so we have chosen to
set the input values for the view-window as 0 to 20. To do so, enter the
following values: X X min :
; Xmax: ; scale: .
Similarly, the height of the trees must be greater than or equal to 0; so
Y Y min :
we have chosen to enter the following values: ; Ymax:
; scale: .
Press to return to the equation screen, and press (DRAW) to
draw the graph of the equation in the view window you defined.
