Stretch the frog by changing the multiplier (point B on the horizontal axis.)
Change the height of the original (green) frog by moving the point D up or down.
The red frog is the result of stretching.
You can also use this tool to multiply two numbers, such as 0.75 times 1.2. Double click on B under "Free objects", and change it to (0.75,0). Double click on D and change it to (1,1.2).
What happens when you stretch by a small number (between 0 and 1)?
What happens when one or both of the factors are negative?
