设函数f(x)在区间(a,b)内满足 ,则函数在此区间内是( )[img=129x22]17a3d9fe641e088.png[/img]
举一反三
- 设函数f(x)在区间(a,b)内满足,则函数在此区间内是( )[img=215x37]17a3da5a468c888.png[/img]

- 函数y=f(x)在区间[a,b]上连续,在区间(a,b)内可导,且[img=63x21]17e0a8613fd61e0.png[/img],则函数y=f(x)在区间[a,b]上单调增加。( )
- 函数f(x)在区间[img=39x25]1803b946720fd55.png[/img]上连续,则f(x)在区间[img=39x25]1803b946720fd55.png[/img]上一定有界。
- 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。
