The domain of the function f(x)=1/x is? A. All real numbers B. All positive real numbers C. All negative real numbers D. All real numbers E. xcept 0 相关知识点: 试题来源: 解析 D。解析:函数 f(x)=1/x,当 x=0 时,分母为 0,无意义。所以定义域是所有实数除了 0。
【题目】A function f has the set of complex numbersfor its domain and range. It has the propertythat, for any two complex numbers z and w,|f(z)-f(w)|=|z-w|. Explain why f(1)-f(0) must be non-zero.T he function g is defined by g(z)= racf(z)-f(0),Show that g has...
A. (-∞, 0) ∪ (0, +∞) B. (-∞, +∞) C. (0, +∞) D. [0, +∞) 相关知识点: 试题来源: 解析 A。因为对数函数的真数必须大于 0,所以 |x| > 0,即 x ≠ 0,定义域为 (-∞, 0) ∪ (0, +∞)。选项 B 包含了 x = 0,不符合对数函数的定义;选项 C 只包含正数;...

结果1 题目 Let z=f(x,y) be a function with domain D and (x_0,y_0)∈ D, if f(x,y)≤ f(x_0,y_0) for all (x,y)∈ D then f has (an) ___ at (x_0,y_0). 相关知识点: 试题来源: 解析 absolute maxima 反馈 收藏 ...
For steps, review Clean Up Server Metadata. Demoting the last domain controller in a domain requires Enterprise Admins group membership, as this removes the domain itself (if the last domain in the forest, this removes the forest). Server Manager informs you if the current domain controller ...
