Original question and givens

On all R, f has ascending coefficients [10, 23, 0, 3], constant term first. Let F=F0+C with zero-constant primitive F0. Choose C so that F(-3)=10/2. Use reduced positive-denominator fractions, retaining /1 for integers.

  • G001 — On all R, f has ascending coefficients [10, 23, 0, 3], constant term first. Let F=F0+C with zero-constant primitive F0. Choose C so that F(-3)=10/2. Use reduced positive-denominator fractions, retaining /1 for integers.

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.
