高考综合题往往是问题情境较复杂,图形线条繁多.求解此类问题需要同学们具有较强的抽象思维能力,适时根据问题的结构、数学对象的内涵和外延,灵活转换思维角度,运用分解、分割、分离、分情况等策略,将大题转化为一些小题.例题(2014年高考江苏卷第19题)已知函数f(x)=e x+e-x,其中e是自然对数的底数.(1)证明:f(x)是R上的偶函数.(2)若关于x的不等式m f(x)≤e-x+m-1在 Comprehensive questions of college entrance examination are often more complex problem situations, a variety of graphic lines.To solve these problems require students to have a strong abstract thinking, timely according to the structure of the problem, the mathematical content of the connotation and extension of the flexible conversion of thinking point of view, the use of decomposition, (2014), Jiangsu Province Volume 19 Question) known function f (x) = e x + ex, where e is the natural logarithm of the base (1) Proof: f (x) is an even function on R. (2) If the inequality mf (x) ≤ e-x + m-
