在平面直角坐标系中,将一次函数图象进行平移,求移动以后的一次函数解析式,或者已知平移以后的一次函数解析式求平移之前的一次函数解析式,是学生学习中的一个难点,但也是一个充满乐趣,值得探究的知识点.笔者尝试课堂之余让学生自主探究,相互讨论,探求其方法和规律,略有收获.一次函数图象的平移包括上下平移和左右平移,不论是哪种平移都可以用一种求解析式的方式来推导另外的几种求解,而且一 In the Cartesian coordinate system, it is difficult for students to learn to translate the image of primary function by the first-order function after the movement or the first-order function after the translation. , But also a full of fun, it is worth to explore the knowledge of the point I try to allow students to explore the classroom, to discuss each other to explore its methods and laws, a little harvested. Translation of a function of the image, including panning up and down and left and right translation, What kind of translation can be used in a solution to the way to derive several other solutions, and a
