G001 — On all R, f has ascending coefficients [5, 13, 14, 1], constant term first. For arbitrary oriented endpoints a=-2,b=-1,c=-15, give (I(f,a,b),I(f,b,c),I(f,a,c)) using the scoped polynomial moments. Use reduced positive-denominator fractions, retaining /1 for integers.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.
