点P在反比例函数y=﹣的图象上，过点P分别作坐标轴的垂线段PM、PN，则四边形OMPN的面积=（ ）A. B. 2 C. 2 D. 1 答案：【答案】C【解析】在反比例函数y=图象上任取一点，过这一个点向x轴和y轴分别作垂线，与坐标轴围成的矩形的面积是定值|k|.解：∵点P在反比例函数y=﹣的图象上，∴过点P分别作坐标轴的垂线段PM、PN,所得四边形OMPN的面积为|−2|=2.故选C.--Have you heard of Liu Qian from Taiwan? --Sure! His magic performance is amazing for people forget.A. so, that B. such, that C. too, to D. enough, to
