Detailed method of using custom transformation translation function image in Geometry Sketchpad

1. Create function image. [Draw] - [Draw new function], enter [x], [ ], [3] in the function editor, [OK] to get the analytical formula of the function [y=x 3].

2. Mark the points on the vector translation image. Use the [Point Tool] to draw point Q outside the straight line, select point O and point Q, and go to the menu [Transform] - [Mark Vector]. Use [Point Tool] to construct a point P on the image, select point P, [Transform] - [Translate] to obtain point P’.

3. Select points P and P’, [Transform] - [Create custom transformation], named [Translation Image].

4. Select the function image, [Transform] - [Translate Image]. Move point Q and the image will follow.

Tip: In step 3, after selecting points P and P’, use the [Construction]-[Trajectory] command to get the final effect.
