1试题呈现(北京卷第26题)已知y是x的函数,自变量x的取值范围是x>0,下表是y与x的几组对应值。小腾根据学习函数的经验,利用上述表格所反映的y与x之间的变化规律,对该函数的图像与性质进行了探究。下面是小腾的探究过程,请补充完整:(1)如图1,在平面直角坐标系中,描出了以上表中各对对应值为坐标的点。根据描出的点,画出该函
1 questions presented (Beijing Volume 26) Known y is a function of x, the value of the variable x is the range of x> 0, the following table is the y and x of several sets of corresponding values. According to the learning function's experience, Xiaoteng explored the image and the nature of the function by using the variation rule of y and x reflected in the above table. Here is Xiaoteng inquiry process, please add the complete: (1) as shown in Figure 1, Cartesian coordinates in the plane, the above table in each of the corresponding value for the coordinates of the point. Draw the letter based on the points drawn
