函数图形的平移变换是课程标准所要求的函数学习的主要内容之一.虽然课本上给出了平移规律,但同学们掌握和运用不好.在此我们一起探讨一下函数图形的平移问题.一、一次函数图像的平移变换一次函数图像平移,变换前后两条对应直线彼此平行.在坐标平面内,互相平行的两条直线解析式中k值相等,b值不同.两条直线的左右平移可以通过它们与x轴的交点坐标呈现,两条直线的上下平移可以通过它们与y轴
The translation of the function graph is one of the main contents of the function learning required by the curriculum standard.Although the translation rules are given in the textbook, it is not good for the students to grasp and use it.We will discuss the translation of the function graph together. , A function of the image transformation of the transformation of the linear function of the first image shift, transformation before and after the two corresponding lines parallel to each other in the coordinate plane, parallel to each other two straight line analytical equation in the same value of b, b value is different. Through their coordinates with the x-axis intersection, two straight lines up and down translation through their y-axis
