Ability training is the basic starting point and the reality of the mathematics teaching activities carried out under the new curriculum standards. It is also a concrete reflection of carrying out and implementing the requirements of the new curriculum standard ability training. It is also an important manifestation of the current national society in promoting quality education and personnel training. Vivid portrayal. As one of the important parts of the chapter system of junior high school geometry, the one-time function chapter plays the role of linkages in the entire knowledge system. I explain a case of function problems, ”known y-4 is proportional to x, and x =
