21 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 and select Linear Explorer.
The left half of the display shows the graph of a linear function. The right half shows the general form of the
equation being explored at the top and, below it, the current equation of that form. The keys you can use to
manipulate the graph or equation appear below the equation. The x- and y-intercepts are given at the
bottom.
