函数恒成立问题,是近年高考试题的一大热点.07年的高考试题中,多处涉及到恒成立问题,而恒成立问题与函数的单调性联系紧密.下举例说明:一、a≥(fx)(或a≤(fx))对x∈D恒成立问题
The establishment of functional constants is a hot topic in recent high-achieving examinations. In the high examination questions of the year 2007, multiple problems related to permanent establishment were involved, and the constant establishment problems were closely related to the monotony of functions. The following examples illustrate: a. Fx) (or a ≤ (fx)) holds true for x∈D
