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 y = ax and y = ax + b as the values of a and b change.

Open the app Press Iand select Linear Explorer.

The left half of the display shows the graph of a linear function. The right half shows the general
