Original question and givens

Integer polynomials have ascending coefficients f=[-9, 4, -2, 1], constant term first. For c=1, give the complete ascending coefficients of f(x+c), not merely a value at one point.

  • G001 — Integer polynomials have ascending coefficients f=[-9, 4, -2, 1], constant term first. For c=1, give the complete ascending coefficients of f(x+c), not merely a value at one point.

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
