互为反函数的图象的交点问题贵州瓮安一中周承欢用方程组ｙ＝ｘ，ｙ＝ｆ（ｘ）｛求方程ｆ（ｘ）＝ｆ－１（ｘ）的解、求ｆ（ｘ）与ｆ－１（ｘ）图象的交点，为什么有时无解、有时漏解呢？这是因为互为反函数的两个函数的图象，有的不相交，而相交的其交点不一定都在直线ｙ... The intersection point of images with inverse functions each other Guizhou Zhou Ancheng Zhou Chenghuan uses the equations y=x, y=f(x){to find the solution of the equation f(x)=f-1(x) and find f( x) Why is there sometimes no solution and sometimes missing solution at the intersection with the f-1(x) image? This is because the images of the two functions that are inverse functions of each other are disjoint, and the intersecting intersections are not always on the straight line y...
