Controlling What Appears on a Graph Screen
Example Enlarge the graphs of the two expressions shown below fi ve times on
both the x - and y -axis to see if they are tangent.
Y1 = (
x + 4)( x + 1)( x – 3), Y2 = 3 x + 22
Use the following V-Window settings.
Xmin = –8, Xmax = 8, Xscale = 1
Ymin = –30, Ymax = 30, Yscale = 5
