Question 29932: Primitive Constant Selected by an Explicit Anchor

Original question and givens

On all R, f has ascending coefficients [-6, 7, -1, 3], constant term first. Let F=F0+C with zero-constant primitive F0. Choose C so that F(-3)=-6/1. Use reduced positive-denominator fractions, retaining /1 for integers.
