Plot of (x-4)^(3)*x^2*(x+5) missing one part of the graph
The graph of (x-4)^(3)x^2(x+5) has also a root at x = -5 but fooplot is not plotting this.
How it should look like: http://www.matheretter.de/tools/funktionsplotter/?%28x-4%29^3x^2%28x+5%29

How to solve the bug?
I think it has to do with the dx that javascript uses in the background to calculate the value of the function at each x. If you increase the range -- like http://fooplot.com/plot/swjv8xfhul -- it works just fine
This is weird, changing the range really plots the roots.
Here is another example that should have a root at about x=5.12 but it is not drawn: http://fooplot.com/plot/r98uwtaddy
Can this be solved? (I mean without the workaround of the range setting - users will not know...)
