函数与数列、不等式的综合题综合性强,方法灵活,思维量大,难度偏高,每一道题对学生的思维能力,综合应用知识解答问题的能力都是一次严峻的考验,而对这类题的研究也有助于学生学习、思维、应用能力的提高,下面和同学们分享一道函数综合题的几种解法。例已知函数f(x)=|x-a|-lnx(a>0).(1)若a=1,求f(x)的单调区间及f(x)的 Function and sequence, the inequality of comprehensive synthesis of comprehensive, flexible, large amount of thinking, high degree of difficulty, each question on the students ability to think, comprehensive application of knowledge to answer questions is a severe test of the ability of this type The study also helps students improve their learning, thinking and ability to apply. Here are some ways to share a functional synthesis question with their classmates. For example, we know the function f (x) = | x-a | -lnx (a> 0). (1) If a = 1,
