我们在学习一次函数、反比例函数、二次函数时,都会研究函数图像的平移,并求出平移后相应的函数关系式.对于不同函数图像的平移,我们往往会用不同的方法求出相应的函数关系式.笔者通过探索发现,只要用一种方法,就能求出这些函数图像平移后的关系式.一、一次函数图像的平移把一次函数y=2x+1的图像向上平移2 When we study a function, an inverse function and a quadratic function, we study the translation of the function image and find the corresponding functional relationship after translation. For the translation of different function images, we often find the corresponding Function relationship.I discovered through exploration, as long as a method, you can find the translation of these functions after the relationship between the image.First, the translation of the image of a linear function of the function y = 2x +1 image translation 2
