Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and activated. (click here to install Java now)

Move the sliders to investigate how changing these values affects the graph

1) How does changing the coefficient affect the graph? Explain in your journal.
2) For what value of the coefficient is the graph of the function a horizontal line?
3) How does changing the value of the constant move the graph? Explain.
