The graph shows a function. What is the equation of the function? A. y = x + 5 B. y = 2x + 3 C. y = 3x - 1 D. y = 4x - 2 相关知识点: 试题来源: 解析 C。观察图像可知,直线的斜率约为 3,截距约为 -1,所以函数方程为 y = 3x - 1。A 选项斜率为 1,截距为 5,不符合。
Below the graph, the coordinates of the point and the equation of the tangent line are shown.Coordinates of point: The graph below shows a function y=f(x), together with a red point on the curve. You can move the point along the ...
A. linear function B. quadratic function C. exponential decay function D. logarithmic function 相关知识点: 试题来源: 解析 C。本题主要考查不同函数图像的性质。线性函数一般不会在 x 趋向无穷时函数值趋向零;二次函数也不会有此性质;对数函数在特定情况下函数值趋向无穷或特定值,而不是零。指数衰减函数...
流程图有助于了解和估算一个过程的质量成本 3.散点图如果存在相关性,就可以画一条回归线,来估算自变量变化将如何影响因变量的值。 4.矩阵图在行列交叉位置展示因素、原因和目标之间的关系强弱。 从网上看都是选矩阵图 C ,不过我认为这道应该选散点图 D ,是表示两个变量的关系。
【答案】：C （ ）是显示了两个变量之间关系的一种图表。A 直方图 B 流程图 C 散点图 D 矩阵图 此题考查质量管理的七种工具，其中散点图可以显示两个变量之间是否有关系，一条斜线上的数据点距离越近，两个变量之间的关系就越密切。
In many cases, some other properties of the function can also be seen directly from the graph.For example, the following graph shows the air temperature as a function of the time in some place during 24 hours in January. That is, the time is regarded as the input, and the air ...
This graph shows the function y = √x. Note that there are two possible solutions on the y-axis for every value of x. Two of those solutions correspond to x = 4: y = 2 and y = -2. Both solutions are, mathematically, equally valid. But there’s only one physical Universe that we...
The graph shows a steady increase. Which of the following best describes this? A. rise gradually B. increase rapidly C. drop suddenly D. remain unchanged 相关知识点: 试题来源: 解析 A。解析:“rise gradually”表示逐渐上升,符合图表中稳定增加的描述。“increase rapidly”是快速增加;“drop suddenly...
解析 B 【详解】 句意:图表显示7月份交通事故的数量下降到208起。 考查短语辨析。a number of许多;the number of……的数量;a large amount of大量的;the large amount of错误搭配。根据“fell to 208”可知此处指交通事故的数量。故选B。反馈 收藏 ...
[选择题] The( )is a graph that shows the relationship between two variables. A. histograms B. flowcharts C. matrix diagrams D. scatter diagrams 相关知识点: 试题来源: 解析 D 正确答案:D参考解析: 散点图是显示两个变量之间关系的图。
