The figure above shows the graph of a function f, dined by f(x)=|2x|+4 for all numbers x. For which of the following functions g dined for all The figure above shows the graph of a function f, dined by f(x)=|2x|+4 for all numbers x. For which of the following functions g dined for all numbers x does the graph of g intersect the graph of f ?

　　A g(x)=[1]x–2

　　B g(x)=[1]x+3

　　C g(x)=[1]2x – 2

　　D g(x)=[1]2x+3

　　E g(x)=[1]3x – 2

　　这个题就是问两个函数图象相交的问题，根据观察，要与这个折线相交的直线的斜率满足的条件是要么是正斜率比2大，要么是负斜率比-2小，因此只能选E了。获得更多gre考试咨询点击进入>>>>澳际免费咨询顾问或联系QQ客服：800004500
