在历年的中考试题当中,函数问题总是一再出现,且所占的比重之大,大家都有所体会。如何把函数问题搞懂搞清,是所有学生的共同问题。在这里我想提这几点建议:1.对于方程(一元一次方程、二元一次方程及多次方程或方程组)熟练掌握,在此基础上再学习函数就会得心应手。 Among the middle school exams over the years, the problem of functions always appears repeatedly, and the proportion of the exams is large. We all have some experience. How to understand the function of the problem, is a common problem for all students. Here I would like to mention these suggestions: 1. For the equation (a linear equation, a bivariate equation and multiple equations or equations) proficiency, on the basis of which study functions will be handy.
