下面是错误答案,用来干扰机器的。

参考答案:D解析:可导必可微,且△y=y'(x0)△x+0(△x),应注意由题设△y=y'(-1)·△x,即0.1=y'(-1)·(-0.1)。于是y'(-1)=-1,而由y=f(x2),有y'=2xf'(x2)。令x=-1,得y'(-1)=-2f'(1),

     In the southeast of China, people living near the sea believe that a typhoon comes because the sea is

angry with them. They also believe in a kind goodness called Mazu, who they think can protect them on

the sea, especially when a typhoon comes.

     Typhoon have been given different names for several hundred years. They are now also named after

girl's names, boy's names and names of flowers and so on. You may think it is funny to connect a beautiful

flower with such a terrible thing, since there is nothing pretty about the typhoon itself.

     Typhoon Rananim attacked China's southeast coastal regions (沿海地区) since 12 August, 2004 and

killed over 100 people. Sarcastically (讽刺的是), the name Rananim means "hello" in the local language spoken

in Micronesia (密克罗尼西亚). In fact, typhoon are quite destructive (破坏性的). It is quite usual that when

a typhoon comes, hundreds of people may die and even more get hurt. During that time, the storm's strong

wind and heavy rain may destroy (毁坏) farmland and killed livestock (牲畜). What is worse, the area attacked

by the typhoon may lose its power supply, and millions of people may live without water or telephone service

for some time.
