函数f(x)=ax+(b/x)是近年来高考应用题的数学模型之一,主要是求它的最值.一般的解法是根据单调函数的定义来判断其增减性,再利用函数的单调
The function f(x)=ax+(b/x) is one of the mathematics models of the college entrance examination problem in recent years. Its main purpose is to find its maximum value. The general solution is to judge the increase or decrease of the monotonic function based on its definition and reuse. Monotonous function
