若f(x)与f(x)都是n次多项式,且在n+1个互异点[img=15x17]18030752905fe56.png[/img]上[img=89x25]18030752981507a.png[/img],则f(x)=g(x)
举一反三
- 若f(x)与g(x)都是n次多项式,且在n+1个互异点上函数值相等,则[img=90x25]18030751de017bc.png[/img]
- 若f(x)+f(-x)=0, 则[img=95x39]17da608af452d96.jpg[/img]. 若f(x)=f(-x), 则 [img=170x38]17da60541207426.jpg[/img]
- 设F(x),G(x)都是函数f(x)在区间I上的原函数,则下面( )不正确 A: F(x)=G(x)+lnC B: F(x)=G(x)+C C: F(x)=G(x)-C D: F(x)=G(x)+e[img=9x12]180344b77e7e83a.png[/img]
- 令F(x):x是有理数,G(x):x是实数。将命题“所有的有理数都是实数,但有的有实数不是有理数”符号化为() 未知类型:{'options': ['17e0a83a4157352.jpgx(F(x)∧G(x))∧[img=8x14]17e0a83a35505d4.jpg[/img]x(G(x)[img=14x9]17e0a73094b5dcf.jpg[/img][img=10x11]17e0a839b915354.jpg[/img]F(x))', ' [img=8x14]17e0a83a4157352.jpg[/img]x(F(x)[img=14x9]17e0a73094b5dcf.jpg[/img]G(x))∧[img=8x14]17e0a83a35505d4.jpg[/img]x(G(x)∧[img=10x11]17e0a839b915354.jpg[/img]F(x))', ' [img=8x14]17e0a83a4157352.jpg[/img]x(F(x)∧G(x))∧[img=8x14]17e0a83a35505d4.jpg[/img]x(G(x)∧[img=10x11]17e0a839b915354.jpg[/img]F(x))', ' [img=8x14]17e0a83a4157352.jpg[/img]x(F(x)[img=14x9]17e0a73094b5dcf.jpg[/img]G(x))∧[img=8x14]17e0a83a35505d4.jpg[/img]x(G(x)[img=14x9]17e0a73094b5dcf.jpg[/img][img=10x11]17e0a839b915354.jpg[/img]F(x))'], 'type': 102}
- 设函数f(x)具有任意阶导数,且f"(x)=[f(x)]2,则f(n)(x)=______ A: n![f(x)]n+1 B: n[f(x)]n+1 C: (n+1)[f(x)]n+1 D: (n+1)![f(x)]n+1
