由于初中生对变量、函数概念及其性质、图象的认识上的差距,常常造成在与抛物线相关联的数学问题上失分较多。本文拟对中考试题中经常出现的这类问题及其解法作些介绍。 Because junior middle school students have gaps in the concept of variables, functions and their properties, and images, they often cause more points to lose on the mathematical problems associated with parabolas. This article intends to introduce some of these problems and their solution to the problems that often appear in the exam questions.
