Generally speaking, the answers are of little use, because the answers are idealized, which means that all experts can fully understand the questions and then give them as concisely as possible. The answers are basically useless to the candidates after repeated sorting, because they can't remember! ! ! ! Now I'll tell you my thoughts on the next question:

Habitually, when I get the second question, which inequality will f(x) be substituted into, and then the formula on the right will be moved to the left, and the part on the left except 1 will be moved to the right; Only when I arrived at this place did I find that there was something wrong with my thinking! ! ! Why? Because my formula can't be changed any more. At this time, it won't be too difficult to think about science in National Volume 2. Then I'm trying to find a way. After analyzing the topic, it is easy to find that it is necessary to bring in f(x) (you can also see if it is, or write it differently! ! ! ) Since you can't move around, try the one on the same side. Then move the formula on the right to the left, and you will divide the whole formula by,, and you will find that the denominator is (ax+ 1) multiplied by the x power of e; The molecule is (e- 1 x power) multiplied by (ax+ 1)-e x power multiplied by x, and the right side is 0. Looking at the known x>0, we can know that the above score can be converted into (e- 1 x power) multiplied by (ax+ 1)-e multiplied by X and (ax+ 1) < 0 to x>0 or equal to zero is a constant problem! ! ! ! At this point, you basically know that your thinking is completely correct. Try it yourself if you don't believe me! ! ! ! The following analysis is divided into two different situations of two symbols, and you should be able to do it. Do it yourself! ! !

Note: After the final separation, the long formula will be difficult to hold, so look at (ax+ 1). If it is greater than 0, you can get that & gt0 is a constant, so the long formula must be
