本題是一道典型的導(dǎo)數(shù)綜合應(yīng)用問(wèn)題，（1）問(wèn)已知函數(shù)的單調(diào)性求參數(shù)的取值范圍，先對(duì)所給函數(shù)進(jìn)行求導(dǎo)轉(zhuǎn)化為恒成立問(wèn)題，再根據(jù)式子的結(jié)構(gòu)采取恰當(dāng)?shù)姆椒ㄟM(jìn)行處理。（2）問(wèn)是一道函Jyp/yKtRHV8fB0nMTkki+w==數(shù)圖像交點(diǎn)問(wèn)題，實(shí)際上也是一道方程根的問(wèn)題，①小問(wèn)求參數(shù)的取值范圍，注意轉(zhuǎn)化;②小問(wèn)是一道不等式證明問(wèn)題，實(shí)際上也是一道極值點(diǎn)偏移問(wèn)題。本題對(duì)同學(xué)們的邏輯推理能力、運(yùn)算求解能力、分析問(wèn)題和解決問(wèn)題的能力等多種思維能力要求較高，求解過(guò)程中要根據(jù)式子的結(jié)構(gòu)特點(diǎn)靈活選用恰當(dāng)?shù)姆椒▉?lái)解決。
