Function app transform question

[jte]

The transform feature in the Function app was, at first, intended to be used when teaching basic transformations on a handful of different basic types of functions (which included quadratic but not cubic polynomials). As it was being developed some alternative uses became clear (e.g., using it as a tool to enact transformations conveniently [via gestures] rather than teach about transformations; to simplify expressions; to handle generic expressions rather than just a handful of basic types). I can't speak towards there being any future versions of the software, but some adjustments to this feature are a natural thing to consider. (Depending on scheduling, priorities, etc.)

The Simplify button converts the current function to the current form chosen for it and uses a precision, for coefficients, that is appropriate to the current plot view. There are no forms for cubics in r10077 so there is no Simplify button. (Adding some support for collapsing affine portions of generic functions would change this, as would adding support for cubic polynomials.)
