Question 56
Find all monic polynomials $f$ with integer coefficients satisfying the following condition:
There exists a positive integer $N$ such that for every prime $p \gt N$, $p$ divides $2(f(p))! + 1$.
There exists a positive integer $N$ such that for every prime $p \gt N$, $p$ divides $2(f(p))! + 1$.
