( x→0) limf(x)=( x→0) limx=0
(x→1左) limf(x)=1、(x→1右) limf(x)=1-1=0,左極限不等右極限,極限不存在.
(x→2)limf(x)=(x→2)lim(x-1)=2-1=1
設(shè)函數(shù)f(x)={x-1,x≥1,x,-1

- 函數(shù)在0處有定義,f(0)=1,f'(0)=1,limf(x)/x=?(x趨向于0)
- 設(shè)函數(shù)f(x)在x=a處二階可導(dǎo),又limf'(x)/(x-a)=-1,則() A.x=a是f(x
- 若函數(shù)f(x)可導(dǎo),則limf(1+△x)-f(x)/3△x等于
- 證明:若函數(shù)f(x) 在(-∞,+∞) 內(nèi)連續(xù),且limf(x) 存在,則f(x) 必在(-∞,+∞) 內(nèi)有界.
- x→a limf(x)=A ,則函數(shù)f(X)在a處有沒(méi)有意義
