The graph of f(x)=a*x^b+2 passes through P(1|1) and Q(2|-2) . Find f(x). 高三党看不懂,求解答过程.
狮子爱2598
这是个貌似是初中的题吧,只不过题干是英文的.就是告诉了2个点,求f（x）由题意-2=a*2^b+2 1=a+2 解得a=-1,b=2 f(x)=-x^2+2
已经知道了，只是坐标表示方式不同，谢谢了

扫描下载二维码use a graph to find the zeros of the functionf(x)=2^(x)-5（是2的x次方.）这里的零点指的是什么?,与x-axis or y-axis 的交点?还是别的什么?不用翻译,
就是f(x)=0的时候,x的值.也就是方程的根.2^x=5 x=log2(5),画个图表示一下就可以了.

卡琳娜pasina -无法找到的话
现在我们已经谈了一段时间;
你让我水手都想弄清楚
男孩，我不知道什么对你说
但是你让我为你feelin一些实物方式
和我所知道的是，当我们同在一起
没有人可以让我感觉你的方式婴儿
我希望每一刻可以永远延续下去
这是很难解释的方式，我为你感到
（我实在无法找到的话）
你让我自己松动
在我尝试说
它是那么的难决高下
不能不feelin这种方式
每次我靠近你就像我的心很薄弱获得。
感觉就像我失去我的呼吸马金很难说。
我不觉得这句话
无法找到的话
我不觉得这句话
我不觉得这句话
现在我知道我来过有点儿害羞
但很难说我心里在想些什么的...
