傻傻的双子
给你举个例子。Hecomesintheclassroom,abookinhand。上句中book表示他拿了本书,修饰他进教室时的情况,表示伴随的状况。此时的名词book作状语。

求导,y'=dy/dx=6x^2+6x-12=6(x-1)(x+2)所以,当x1时,y'>0;当-2当x=1或-2时,y'=0;所以原函数在(-3,-2]上单调递增,在[-2,1]上单调递减,在[1,4)上又单调递增。所以,在(-3,4)上,当x=-2或x->4时,函数得到最大值然后代入原函数分别算一下-2和4算出来哪个大。同理,在(-3,4)上,当x=1或x->-3时,函数取得最小值然后代入原函数分别算一下1和-3算出来哪个小。最后的结果是,当x->4时,原函数的值最大;当x=1时,函数取得最小值7。所以,函数。。。在(-3,4)上没有最大值。当x=1时,函数。。。在(-3,4)得到最小值,最小值为y=7.
