设函数[img=34x25]1803a5759af95f1.png[/img]连续,且[img=174x50]1803a575a6ef8b9.png[/img],则[img=51x25]1803a575afb8578.png[/img] .
举一反三
- 设f(x)在[img=51x25]1803957723f3d8d.png[/img]上连续,则 [img=213x50]180395772e4bd2f.png[/img] ( )
- 设f(x)在[img=51x25]1803957567fd771.png[/img]上连续,则 [img=213x50]18039575729618f.png[/img] ( )
- 设函数f(x)在区间[img=61x25]1802fa024965265.png[/img]中连续,且[img=85x25]1802fa0251a79d3.png[/img]存在且有限,则f(x)在区间[img=61x25]1802fa024965265.png[/img]可能无界。
- 设函数f(x)在区间[img=61x25]1802fa0388e05e0.png[/img]中连续,且[img=85x25]1802fa03909dda1.png[/img]存在且有限,则f(x)在区间[img=61x25]1802fa0388e05e0.png[/img]可能无界。
- 设函数对任意x均满足f(1 + x) = af(x), 且[img=53x21]17da62a357b68ea.png[/img]b, 其中a, b为非零常数, 则() 未知类型:{'options': ['f(x)在x = 1处不可导 .', 'f(x)在x = 1处可导, 且[img=51x21]17da62a36fc6964.png[/img]a.', 'f(x)在x = 1处可导, 且[img=51x21]17da62a36fc6964.png[/img]b.', 'f(x)在x = 1处可导, 且[img=51x21]17da62a36fc6964.png[/img]ab.'], 'type': 102}
