## 1. Evaluate with Fixed Bivariate Coefficient Roles

Use the declared real polynomial R²→R with coefficients=[-12, -2, -3, 1, -1, -1] in the fixed order [1,x,y,x²,x*y,y²]. Keep the two coordinate roles distinct. These explicit slices establish no global continuity, differentiability or vector-valued-function claim. x=-2, y=-3. Give (coefficients,x,y,exact polynomial value).

View answer and explanation([-12, -2, -3, 1, -1, -1], -2, -3, -10)

These explicit slices establish no global continuity, differentiability or vector-valued-function claim. original points=[[0, 0], [1, 0], [0, 1]], aligned claimed values=[3, 2, 0]. Give (coefficients,every [x,y,claimed value,actual value,match?] row,all listed rows match?). Preserve point order, repeated points and value alignment; an empty table has a vacuously true all-match flag.

Recompute every declared point without sorting away its claimed value. Even all-match does not prove global function equivalence, continuity or differentiability. This explicit finite/exact slice does not automatically become a general infinite conclusion. The exact result, retaining the requested order, is ([3, -2, -2, 1, -1, -1], [[0, 0, 3, 3, Yes], [1, 0, 2, 2, Yes], [0, 1, 0, 0, Yes]], Yes).
