《全日制义务教育数学课程标准(实验稿)》要求学生“能结合图像对简单实际问题中的函数关系进行分析”.从这一目标出发,近几年各地的中考试卷中,出现了反映实际问题的函数图像选择题.这些试题有效地考查了学生探索具体问题中的数量关系和变化规律的能力.现以中考试题为例,对这类问题的解法作如下探讨. The “Full-time Compulsory Education Mathematics Curriculum Standard (Experimental Draft)” requires students to “be able to combine image analysis of functional relationships in simple practical problems.” From this goal, in the mid-term examination papers in various places in recent years, Functional image multiple-choice questions that reflect actual problems. These test items effectively examine the ability of students to explore quantitative relationships and changes in specific issues. Take the middle-test questions as an example to discuss the solution to such problems as follows.
