The method of drawing function images by using the stroke method is not limited to a function, but is suitable for drawing any image of a function. The following is an example of function y=x3, which describes how to draw a function image using the geometry artboard to draw points.
The following steps are described:
1. Execute the draw-Define coordinate system command, create a new coordinate system, and set the label of the origin coordinates to O.
2. Select the x-axis of the coordinate system, execute the "construct"-"point on Axis" command and construct point B.
3. Select point B, and perform the "measure"-"horizontal" command to measure the horizontal-axis xb of point B.

4. Select the horizontal axis xb of point B, execute the "measure"-"Calculate" command and calculate the value of xB3 in the New Calculation dialog box that pops up.

5. Select the horizontal axis xB and measure xB3 of Point B, and execute the plot-draw point (x, y) command to Plot point C (Xb,xb3).

6. Select point C and Point B (the order must not be wrong), execute the "construct"-"track" command, you can draw out the function y=x3 image, execute the "plot"-"Hide Grid" command, the coordinate system in the grid hidden.

7. Execute the "file"-"Save" command.
The above content describes the use of geometric drawing points to draw the function of the image, mainly to measure the coordinates of the point, a lot of contact, I believe you can master the drawing skills.
