含參指對(duì)函數(shù)的單調(diào)性問(wèn)題不僅涉及了參數(shù)，還涉及了指數(shù)函數(shù)式、對(duì)數(shù)函數(shù)式.這類問(wèn)題的難度一般較大.很多同學(xué)在面對(duì)這類問(wèn)題時(shí)不知如何下手，下面結(jié)合實(shí)例探討一下，解答含參指對(duì)函數(shù)的單調(diào)性問(wèn)題的思路.

一般地，對(duì)于指對(duì)函數(shù)問(wèn)題，我們通常需運(yùn)用導(dǎo)數(shù)法求解，通過(guò)對(duì)函數(shù)求導(dǎo)，討論導(dǎo)函數(shù)與函數(shù)單調(diào)性之間的關(guān)系來(lái)判斷（剩余1589字）
