This applet demonstrates the [b]domain and range[/b] of a function as well as stating the [b]monotonicity of the functions[/b]. 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]n-slider[/color].[br][list][br][*]The [color=#0a971e]Domain[/color] is the [color=#0a971e]green[/color] line.[br][*]The [color=#1551b5]Range[/color] is the [color=#1551b5]blue[/color] line.[br][*]You can drag [color=#c51414]red[/color] points with your mouse.[br][/list]

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