Using GeoGebra to make a graph with arrows
This is a dynamic worksheet created by GeoGebra.
The graphing window on the right is called the Drawing Pad. To zoom in or out, click in the drawing pad and roll the mouse wheel (if you have one!). To slide the graph left, right, up, or down, click the four-way arrow button, then click and drag in the Drawing Pad. Click on the axes to stretch or compress them. To change the values of a or b, double click on their value in the left-hand window and edit directly. Or, simply select and then press + or - on the numeric keypad to increment/decrement the values by 0.1; doing this repeatedly animates the changing values of a or b. To change the function being graphed, double click "f(x) =" and edit directly. The "Dependent objects" u and v make the arrows on the graph at points (a,f(a)) and (b,f(b)).
Note that the options File, Save, and File, Export do not work on my computer.
