形如ｆ（ｘ）＝Ａａ１ｘ＋ｂ１＋Ｂａ２ｘ＋ｂ２（＊）的函数可化为以下两类：（Ⅰ）ｆ（ｘ）＝ｍｘ＋ａ＋ｎｘ＋ｂ；（Ⅱ）ｆ（ｘ）＝ｍｘ＋ａ＋ｎｂ－ｘ．本文借助解析几何的方法研究（Ⅰ）、（Ⅱ）的值域问题，从而解决了形如ｆ（ｘ）＝Ａａ１ｘ＋ｂ１＋Ｂａ２ｘ＋ｂ２...
A function of the form f(x)=Aa1x+b1+Ba2x+b2(*) can be classified into the following two types: (I)f(x)=mx+a+nx+b; (II)f(x)=mx+a+nb-x. In this paper, the value domain of (I) and (II) is studied by means of analytic geometry, which solves the problem such as f(x)=Aa1x+b1+Ba2x+b2...
