Because of its rich content and more knowledge, the inverse proportion function is one of the key contents of the senior high school entrance examination questions.In the middle school entrance examination questions in recent years, a large number of “small, clever, live” fill in the blank, multiple choice where the inverse proportion function and the area In particular, the test questions are favored by the proponents.This test questions are new in form and comprehensive, focusing on the nature of the function images and various mathematical ideas, from the 2013 senior high school entrance examination math test questions, For the majority of readers reference. First, the coordinates of the area from the point
