关于无理函数ｆ（ｘ）＝ｍｘ＋ｌ＋ｎａｘ２＋ｂｘ＋ｃ，ｇ（ｘ）＝ｍｘ＋ｌ＋ｎａｘ＋ｂ和φ（ｘ）＝ｍａｘ＋ｂ＋ｎｃｘ＋ｄ的值域的求法，有关杂志上发表了不少文章，介绍了多种方法．本文试图构造直线与圆锥曲线，通过对它们位置关系的讨论来求此类函数的值域．这种方...
Regarding the method of calculating the range of the irrational function f(x)=mx+l+nax2+bx+c,g(x)=mx+l+nax+b and phi(x)=max+b+ncx+d, many articles have been published in the magazine. This paper attempts to construct straight lines and conic curves, and find the range of such functions by discussing their positional relations. This side...
