一道数学数学题目(英文的)是关于导函数的!
1.Sketch a graph of the exponential function g(x)=5^x.Then use the derivative formula
f'(x) = lim f'(x)=lim [f(x+h)-f(x)]/h to estimate f'(5),f'(0),and f'(10)(this can be done using the table on you
h→0
graphing calculator,but make sure you write down the formula you entered in place of y1.) Do these values make sense compared to your sketch?From your graph,explain the valuesof lim f'(x) and lim f'(x)
x→-∞ x→∞
翻译过来的大概意思是:给指函数方程 g(x)=5^x 画个草图,然后用导函数公式
f'(x) = lim f'(x)=lim [f(x+h)-f(x)]/h 去估算 f'(5),f'(0),and f'(10) (可以用画图计算器去得到结果.)得出来的值
h→0
和你的图对称吗?或者说符合吗?最后看图解释f'(x) and lim f'(x)
x→-∞ x→∞
我不知道怎么用计算机去得到结果!图是可以画出来的.大家没有画图计算器的话可以用公式推算出来吗?还有就是最后怎么解释f'(x) and lim f'(x)?
x→-∞ x→∞
上面打的太乱了!重打次!

我的理解是要求用定义来求解;ln5 再估算;基本上和你的图没法吻合;基本上斜率是90°的.5^10很大很大.可能他就是这个意思. 


可能外国不会求x→-∞;+∞;所以让大家看图,推测..⊙﹏⊙b汗.你就答 趋向-无穷时 是0; 另


一个是 无穷大啊.有问题;再联络.或说 你是出国的节奏啊~·
