I have a different experience with a recently acquired Ti-30X PRO MathPrint calculator:

Of course, I must admit that I used a technique which comes as close as possible (on a Ti-30X Pro MathPrint calculator) to a symbolic method. Because I don't think we can deduce anything from the operation of a numerical method with a function that is not defined, continuous and differentiable on either side of each root.

I have no idea what methods each of the listed calculators use. But I don't know of any numerical roots finding method that works without the function being defined, continuous and differentiable on either side of each root.
