A. y = x^3 B. y = |x| C. y = 1/x D. y = sin x 相关知识点: 试题来源: 解析 B。本题考查函数的对称性。选项 A,y = x^3 是奇函数,图像关于原点对称。选项 C,y = 1/x 是反比例函数,图像关于原点对称。选项 D,y = sin x 是正弦函数,图像不是关于 y 轴对称。选项 B,y = |...
Which function has a graph that is a straight line parallel to the x-axis? A. y = 5 B. x = 5 C. y = x D. y = x + 5 相关知识点: 试题来源: 解析 A。平行于 x 轴的直线表示 y 值恒定,A 选项 y = 5 中 y 值始终为 5,是平行于 x 轴的直线,故选 A。反馈 收藏 ...
For the graph with various curves, the point (0, -3) lies on which axis? A. x-axis B. y-axis C. Both x-axis and y-axis D. Neither x-axis nor y-axis 相关知识点: 试题来源: 解析 B。点的坐标为(0, -3),横坐标为 0,所以在 y 轴上。
If the graph of a function is symmetric about the y-axis, which of the following could be the function? A. y = x^3 B. y = |x| C. y = 2x D. y = 1/x 相关知识点: 试题来源: 解析 B。关于 y 轴对称的函数是偶函数,A 选项为奇函数,C 选项为奇函数,D 选项为奇函数,B 选项...

highly specialized epithelial cell sub-types with a complete turnover period of 24 to 96 h [2]. The proliferative compartment of the epithelium is localized at the bottom of an intestinal crypt, followed by a gradient of increasingly differentiated epithelial cells along the vertical axis [3,...
Python is a fantastic language with a vibrant community that produces many amazing libraries. I am not a big fan of importing everything at once for the newcomers. So, I am going to introduce a few necessary libraries for now, and as we go on, we will keep unboxing new libraries when ...
A. x = -3 B. x = 3 C. y = -3 D. y = 3 相关知识点: 试题来源: 解析 B。二次函数顶点式 y = (x - 3)^2 + 1 的对称轴为直线 x = 3。选项 A 错误;选项 C 和 D 是纵坐标,不是对称轴。反馈 收藏
Which of the following is a reflection of the graph of y=f(x) in the x-axis? ( ) A. y=-f(x) B. y=f(-x) C. y=f( x ) D. y=-f(-x) 相关知识点: 试题来源: 解析 A The reflection of f(x) in the x-axis is -f(x).反馈 收藏 ...
