How the geometry artboard draws two-time function images

first, draw the image

1, open the geometry artboard, as shown in the picture, click the menu bar "drawing"--draw the new function.

2, in the Open new Function dialog box, first input two items, two items have no square, can be written as x*x.

3, now write the previous item and constant items, as shown in the figure, click the OK button.

4, now the geometric artboard will automatically establish the plane rectangular coordinate system and draw out two function images.

　　Second, adjust the image

1, the whole movement. You can move the entire coordinate system by clicking the move arrow tool with the mouse, and then holding down the coordinate origin in the coordinate system.

2, adjust the data, if you think the data is not accurate, or too detailed, you can click the "Move the Arrow tool", and then in the coordinate system, hold down the x axis of the red dot drag to enlarge or reduce the scale.
