Visual Formula,
Important Graphs,
Inequalities, and
Other Things
The activities this chapter covers allow you to use Visual Formula to work with
many of the equations discussed in previous chapters. Visual Formula equips you
to quickly plot the values you generate using various equations. When you do
this, you can explore how changing such items as the slopes or y-intercepts of
equations changes the shapes of the graphs that result. As you work with Visual
Formula in this chapter, first perform the operations the steps guide you
through. Then retrace the steps and change the values on your own to broaden
and deepen your understanding of the equations and their features. As you go,
experiment. If you create equations that do not work, click the Clear Formula 1
or Clear Formula 2 buttons to erase your work. The topics covered in this chapter
include the following:
n Changing positive slopes of linear equations
n Charting parallel lines
n Adding y-intercept values to shift linear equations
n Working with absolute values
n Creating parabolas
Flipping and shifting parabolas
