Nantong, Taizhou, Yangzhou, Lianyungang, Huai 'an, five cities, 20 13, the third survey and test mathematics test questions (three models), the last question, the last question.
Because g2(x) is a increasing function, no matter what the value of m is, there must be a x0, x 1.
Let g2(x0)x 1? & gtm, that is, m is an arbitrary constant.
For example: m= 10000, there will be a x0, x 1 so that g2(x0)x 1? & gtm，
M approaches infinity, and there will be a x0, x 1 that makes g2(x0)x 1? & gtm，
I don't know if you understand.
