编者按:平时在做函数解答题时,你是否留意过常考的函数有哪些?你总结过以这些函数为考查主体的函数解答题的求解技巧吗?处处留心皆学问,时时答题要总结.如果这部分内容还是你复习的死角和盲区,那就认真看看老师们给出的锦囊妙计吧! Editor’s note: usually do the function to answer the question, you have to pay attention to what functions are often tested? You summarize these functions as the main function of the test to solve the problem solving skills? Always be aware of all knowledge, from time to time to answer the question. If this part of your review of dead ends and blind spots, then take a serious look at the advice given by the teachers it!
