今天刚考完700+,很感谢cd!这么长时间来真的帮了不少忙。 记不住什么题啊,好不容易回忆起来一道数学,发现已经有发在jj里啦,不过把原图补充一下,两个曲线貌似都是三角函数,不过不管是不是都不影响解题的。f(x)纵坐标最高好像只有4,还是满纠结的一道题。。
197.【olivia_xuxu】DS题,有图,三个函数f(x), g(x), h(x),图中画出了f(x)和g(x)两条曲线,未画出h(x),横坐标在0-10之间,纵坐标在1-5之间,f(x)整体大于g(x),问在0<=x<=10这个范围内,是否g(x)<h(x)<f(x)? 1)在0<=x<=10这个范围内,1<=h(x)<=3 2)在0<=x<=10这个范围内,h(x)<=f(x)-g(x)
作文:AI:Society should reject new technologies that risk harm the natural environment.(感觉回忆的这个句子语法有点问题?) AA: 6. The following appeared as part of an article in a magazine devoted to regional life.“Corporations should look to the city of Helios when seeking new business opportunities or a new location. Even in the recent recession, Helios’s unemployment rate was lower than the regional average. It is the industrial center of the region, and historically it has provided more than its share of the region’s manufacturing jobs. In addition, Helios is attempting to expand its economic base by attracting companies that focus on research and development of innovative technologies.” 话说XDF的老师还讲过这道题,写的时候还是有些想不起来了。
