1984年高考数学(理科)第三题(1):设H(x)={0 x≤0/1x>0,画出函数y=H(x-1)的图象此题虽是阶段函数,但只要函数概念清楚,懂得数形结合,会移轴,画出所要求的图象是不困难的,但由于考生对于函数概念及函数的对应法则没有掌握好,以致较多的考生未能正确的解答此题,因此得分很不理想。有鉴于此,中学数学课还应加 1984 college entrance examination mathematics (science) the third question (1): Let H (x) = {0 x ≤ 0/1x> 0, draw the function y = H (x-1) of the image This is a stage function However, as long as the concept of the function is clear, it is not difficult to know the combination of numbers and shapes, shift the axis, and draw the requested image. However, because the candidate’s corresponding rules for function concepts and functions are not well understood, more candidates fail to perform. The correct answer to this question, so the score is not ideal. In view of this, high school mathematics classes should also be added
