近几年来,高考命题中,相继推出了一系列题意新颖,设计精巧,具有一定深度和创新意识的试题,重点是考查考生的迁移能力、理性思维能力和潜在学习能力.其中2004年浙江省高考试卷中的第12道选择题,尤其令人注目,本文试图略加剖析.题目若f(x)和g(x)都是定义在实数集R上的函数,且方程x-f[g(x)]=0有实数解,则g[f(x)]不可能是()
In recent years, college entrance examination propositions have successively introduced a series of questions with novel ideas, exquisite design, and a certain depth and innovation consciousness. The focus is on examination candidates’ migratory ability, rational thinking ability and potential learning ability. Among them, Zhejiang Province in 2004 The 12th multiple-choice question in the high exam paper is particularly noteworthy. This article attempts to analyze it slightly. If the questions f(x) and g(x) are both functions defined on the real set R, and the equation xf[g(x) ]]=0 has a real number solution, then g[f(x)] cannot be ()
