For every value f(x0,y0,z0) you get a single linear constraint on the coefficients of f(x,y,z). If you have enough such constraints, then all coefficients will be uniquely determined, and finding them is straightforward linear algebra that Sage could certainly do efficiently. If you need more details, please respond.
