Using the Graph Window

u To use factor zoom

Example: To enlarge the graphs of the following two expressions, by a factor of 5 in both

directions, to determine whether they come into contact with each other

y1 = (x + 4)(x + 1)(x – 3)

y2 = 3x + 22

(1) On the application menu, tap

(2) On the Graph Editor window, input y1 = (x + 4)(x + 1)(x – 3) and y2 = 3x + 22.

• For details about how to input an expression, see “Function Storage and Graphing

Example” on page 3-1-7 and “3-3 Storing Functions”.

(3) Tap 6 to display the View Window, and then configure it with the following

parameters.

xmin = –8, xmax = 8, xscale = 1

ymin = –30, ymax = 30, yscale = 5

•See “To configure View Window parameters” on page 3-2-1.

(4) Tap $ to graph the functions.

(5) Tap [Zoom] and then [Factor].

• This displays a dialog box for configuring x- and y-axis zoom factor settings.

(6) Input 5 for both the xFactor and yFactor, and then tap [OK].

(7) Tap T, and then use the stylus to drag the screen image so the part you want to zoom

is in the center of the screen.

(8) Tap [Zoom] and then [Zoom In].
