※ 引述《Ommmmmm5566 (鲁蛇虫56)》之铭言：
我算出答案了!!
答案是
f(x)=
2294089816326198083*x^6 /1106897608801064028466148400;
-356922319993209944593x^5 /30747155800029556346281900;
+5600306209092039295072*x^4 /13836220110013300355826855;
-206684979369619767625361*x^3 /36896586960035467615538280;
+1149380099370465559089209117*x^2/1106897608801064028466148400;
-208481498503364481171980957*x /184482934800177338077691400;
+151410004460681514693 /868073286279772906445;
f(9)趋近72, f(8)趋近56, f(7)趋近42, f(6)趋近30, f(5)趋近20,
最重要的是
f(55)趋近66, f(5566)趋近1, 因为5566得第一!!
所以回到原本的题目f(3)趋近6.0083
答案是6.0083!!大家说览趴好!!
