论文部分内容阅读
一次函数是初中数学的“数与代数”中的重要内容,也是中学数学的基础知识.在学习一次函数时,同学们要注意探索数形之间的对应关系和规律,理解实际背景下的基本数量关系和变化规律,发展符号感,增强应用意识.近年来,有关一次函数的图象、性质和应用的题目频频出现在全国各地的中考试卷上.常考题型有填空题、选择题和解答题.这部分内容难度不大,多以中低档题为主.但当一次函数与其他函数知识综合出题时,内容就变得灵活而多样了.
First-order function is an important part in junior high school mathematics “number and algebra ”, also is the basic knowledge of middle school mathematics.When learning a function, students should pay attention to explore the correspondence between the number of forms and laws, understand the actual context The development of the sense of symbols and enhance the sense of application.In recent years, the topic of the image, nature and application of the one-time function frequently appears in the middle school exam papers all over the country. And answer questions.This part of the content is not difficult, mostly in the middle and low title questions.But when a function and other function knowledge comprehensive questions, the content becomes flexible and diverse.
