一道數(shù)學(xué)數(shù)學(xué)題目（英文的)是關(guān)于導(dǎo)函數(shù)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→∞
翻譯過來的大概意思是：給指函數(shù)方程 g(x)=5^x 畫個(gè)草圖,然后用導(dǎo)函數(shù)公式
f'(x) = lim f'(x)=lim [f(x+h)-f(x)]/h 去估算 f'(5),f'(0),and f'(10) (可以用畫圖計(jì)算器去得到結(jié)果.）得出來的值
h→0
和你的圖對(duì)稱嗎?或者說符合嗎?最后看圖解釋f'(x) and lim f'(x)
x→-∞ x→∞
我不知道怎么用計(jì)算機(jī)去得到結(jié)果!圖是可以畫出來的.大家沒有畫圖計(jì)算器的話可以用公式推算出來嗎?還有就是最后怎么解釋f'(x) and lim f'(x)?
x→-∞ x→∞
上面打的太亂了！重打次！
