This applet demonstrates the domain and range of a function as well as stating the monotonicity of the functions. Monotonicity is the function's characteristic known as increasing, constant, or decreasing from left to right.[br][br]You can change the number of segments by dragging the [color=#c51414][b]n-slider[/b][/color].[br]The [color=#0a971e][b]Domain[/b][/color] is the [color=#0a971e]green line[/color].[br]The [color=#0a971e][b]Range[/b][/color] is the[color=#1551b5] blue line[/color].[br]You can drag [color=#c51414]red points[/color] with your mouse.

Graph of the function is polyline. We can change the position of its vertices ([color=#c51414]red points[/color]).[br]Wykres funkcji jest łamaną. Możemy zmieniać położenia jej wierzchołków (czerwone punkty).[br][br]Yuri1969 is a Polish member of the GeoGebra community.
