Stretch Arnold by changing the multiplier (point B on the horizontal axis.)
Change the height of the original Arnold (the one at 1) by moving the point D up or down.
You can also use this tool to multiply two numbers. One factor is the height of the original Arnold (adjust D),
and the other factor is the amount to stretch (adjust B.)
The product is the height of the Arnold at D (the height of the point E).
What happens when one or both of the factors are negative?
