Functions, Tables, Domain and Range
This GeoGebra applet can be used to look at graphs of functions, their tables of values, domain and range. We can enter different functions of in the green input box below the grid, and the minimum and maximum values of in the blue input boxes. The blue column contains the independent variable. The first value is x-min. The rest are generated with a step, controlled by the slider at the lower left corner. The values of the function are calculated in the green column.
Drag the slider to reduce the step and generate more points on the graph of .
Experiment with different functions.
