函数(数列)不等式是高中数学的重点内容,也是高中数学的难点,特别是含参数的不等式更是难上加难.这些不等式中有一类是关于不等式的整数解问题,学生常常感到难以入手.下面笔者试举几例来说明这类问题的常见求解策略.一、直接求出不等式的解集,锁定解集中的具体整数解例1若关于x的不等式ax2≥(3x-2)2解集中整数解恰有两个,求实数a的取值范围.分析这是常见的一元二次不等式,可
Function (series) inequality is the key content of high school mathematics, but also the difficulty of high school mathematics, especially the inequalities with parameters is more difficult.One of these inequalities is the integer solution to inequality problems, students often find it difficult to start. Here are a few examples to illustrate the common solution strategies for such problems: 1. Find the solution set of inequality and solve the specific integers in solution set 1 If the inequality for x ax2 ≥ (3x-2) 2 Solution Concentration There are exactly two integer solutions, the real number a range of values. Analysis This is a common quadratic inequality, but
