一、实验主题利用传统方式(方格纸)和现代技术(几何画板)相结合的方式探究函数图像的性质.二、实验背景苏科版八年级下册教材145页题13:我们知道,一次函数y=x-1的图像可以由正比例函数y=x的图像向下平移1个单位长度得到.函数y=2/(x+1)的图像与反比例函数y= First, the experimental theme of the use of traditional ways (graph paper) and modern technology (geometric drawing board) a combination of ways to explore the nature of the function of the image. Second, the experimental background Suke version of the eighth grade textbook 145 Page 13: We know that once An image of the function y = x-1 can be obtained by shifting the image of the proportional function y = x down by 1 unit length to obtain an image with an inverse function y = 2 / (x + 1)
