The Explorer apps
There are three explorer apps. These are designed for you
to explore the relationships between the parameters of a
function and the shape of the graph of that function. The
explorer apps are:
• Linear Explorer
For exploring linear functions
• Quadratic Explorer
For exploring quadratic functions
• Trig Explorer
For exploring sinusoidal functions
There are two modes of exploration: graph mode and
equation mode. In graph mode you manipulate a graph
and note the corresponding changes in its equation. In
equation mode you manipulate an equation and note the
corresponding changes in its graphical representation.
Each explorer app has a number of equations and graphs
for to explore, and app has a test mode. In test mode, you
test you skills at matching equations to graphs.
Linear Explorer app
The Linear Explorer app can be used to explore the
behavior of the graphs of and as the
values of a and b change.
Open the app Press I and select
Linear Explorer.
The left half of the display
shows the graph of a
linear function. The right
half shows the general
