有界型数列不等式是各种考试中常见的题型,它具有综合性强、涉及知识点多,技巧性要求高等特点,通常在压轴题位置·本文试就近几年的一些考试题型,探索分析处理这类问题的基本思路和方法·一、先求和再比较例1已知函数f(x)对任意实数p,q都满足f(p+q)=f(p)·f(q),且f(1)=31,(1)当 Bounded series inequality is a common type of questions in various examinations. It has the characteristics of strong comprehensiveness, involving many knowledge points, and high skill requirements. It is usually in the position of the finale title. This paper tests some of the exam questions in recent years. The basic ideas and methods to analyze and deal with such problems are as follows: 1. The first-order sum and comparison example 1 The known function f(x) satisfies f(p+q)=f(p)·f(q) for any real numbers p and q. ), and f(1) = 31, (1) when
