The ticks on the horizontal axis still mark off intervals of length 1,
but now the tick marks on the vertical axis mark off intervals of
length 2.
Next you'll translate the plot, moving the interesting part to the center
of the display.
Translating the Plot
After each plot the calculator leaves cross hairs in the center of the
display. (You can't see the cross hairs when the axes are in the center
of the display.) You can use the cross hairs to
digitize
any point on the
display, returning the coordinates of the point to the stack. We'll digi-
tize the point we want to be the center of the next plot and use it to
adjust the plotting parameters.
Move the cross hairs to the indicated position .
