Shift
Graph shift function helps students grasp the relationship between an equation and its graph.
Shift the graph’s location without changing its shape, and the change is immediately reflected
in the equation on the right side of the display.
When the graph of y = x2is shifted downward,
how does this affect the equation?
Select the location of the shift:
move cursor down twice.

Slide show
Slide show assists with teacher preparation. By selecting from the built-in options or cre-
ating your own series of slides, you can demonstrate lessons with minimum preparation
time.
Use the built-in slide show of y = x2to show how the
coordinates change as you move along the graph.
Select y = x
2
and the first slide
appears.
Moving between the values you
can follow the changes in the
graph’s coordinates, making the
nature of the graph easier to
understand.
