How a geometric artboard draws functions in a definite range

The specific steps are as follows:

1. Open the Geometry artboard software, click Draw Point on the Drawing menu, Draw points C ( -2,0), D (3,0), and use the segment ruler tool to construct segment CDs.

Draw point C, D, and construct a segment CD by using the draw Point command on the drawing menu

2. Select the Segment CD, and click Point on line Segment on the Build menu to construct point E. Select Point E, click on the "Measurement" menu "horizontal axis" to point e of the horizontal axis xe.

Construct point E on a segment CD and measure its horizontal axis

3. Click the "Calculate" command under the Data menu to calculate the Y value as shown in the following figure.

Calculate y values by using the calculation command on the Data menu

4. Select the Xe, Y value, click Draw (X,y), get f.

Select Xe, Y-value draw point F

5. Select Points E and F, click "Trajectory" under the "Construct" menu, get the function in the interval [ -2,3] image.

Select Point E and F construct trajectory to get interval function image
