在近几年的高考中,函数不等式是热点,具有综合性强、解法灵活多变的特点,通常是高考的压轴题,具有较好的区分层次和选拔功能.在以往的教学中,我们强调通性通法,通过强化解题过程的规范性,让学生更多的拿过程分.其实,对函数不等式的处理可以仿照选择题的解法,从已有条件入手,充分挖掘隐含信息,从而起到事半功倍的效果. In recent years college entrance examination, the function inequality is a hot spot, with a comprehensive, flexible solution characteristics, usually the finale of the college entrance examination questions, with a better distinction between the level and the selection function.In the past teaching, we emphasize In fact, the treatment of function inequality can be modeled on the solution of multiple-choice questions, start from the existing conditions, and fully tap the implicit information, so that through the standardization of problem-solving process, students can take more points. Play a multiplier effect.
