Functional relationship

原声例句
福尔摩斯基本演绎法第二季

It is unlike you to introduce such a free radical into an otherwise highly functional relationship.

让这样一个不稳定因素加入一个高功能性的关系中不像你会做的事。

真爱如血 第4季

I believe you and I have a very functional and successful business relationship.

我相信我们之间有着非常高效且成功的合作关系。

就业、利息和货币通论（下）

Or-alternatively and perhaps better-we may regard his book as a non-causative investigation into the functional relationship which determines what level of real wages will correspond to any given level of employment.

或者——换句话说，也许更好——我们可以把他的书看作是对函数关系的非因果调查，函数关系决定了实际工资水平将对应于任何给定的就业水平。

就业、利息和货币通论（上）

For 'bearishness' is there defined as the functional relationship, not between the rate of interest (or price of debts) and the quantity of money, but between the price of assets and debts, taken together, and the quantity of money.

因为“看跌”被定义为函数关系，不是利率（或债务价格）与货币数量之间的函数关系，而是资产和债务价格加在一起与货币数量之间的函数关系。

函数 Function (mathematics)

（重定向自Functional relationship）
函数f的部分图像。每个实数的x都与f（x） = x3 − 9x相联系。
（1）一对多。X中的元素3与Y中的两个元素b和c相关。因此这是多值函数，而不是函数。（2）多对一或一对一。X的元素1未与Y的任一元素相关。因此这是偏函数，而不是函数。（3）完全对应且多对一，因此这是从X到Y的函数。此函数可以表示为f =(1, d), (2, d), (3, c)，或

函数在数学中为两集合间的一种对应关系：输入值集合中的每项元素皆能对应唯一一项输出值集合中的元素。例如实数x对应到其平方x的关系就是一个函数，若以3作为此函数的输入值，所得的输出值便是9。为方便起见，一般做法是以符号f,g,h等等来指代一个函数。若函数f以x作为输入值，则其输出值一般写作f(x)，f(x)在英文中读作「f of x」，在中文中常读作「f x」。上述的平方函数关系写成数学式记为f(x)=x^2。函数的概念并不局限于数之间的映射关系，例如若定义函数{\rm{Capital}}( )\ 为每个国家当前的首都，那么给予输入值西班牙就会输出唯一值马德里：{\rm{Capital}}(Spain)=Madrid\ 。气温的分布也能用函数表达，以时间和地点作为参量输入，以该时该地的温度作为输出。表达函数有多种方式，例如解析法是用数学式表达两个变量之间的对应关系，图像法是用坐标系上的函数图形表达两个变量之间的对应关系，列表法用表格表达两个变量之间的对应关系。

Function (mathematics) 函数

（重定向自Functional relationship）
A function f takes an input x, and returns a single output f(x). One metaphor describes the function as a
The red curve is the graph of a function f in the Cartesian plane, consisting of all points with coordinates of the form (x,f(x)). The property of having one output for each input is represented geometrically by the fact that each vertical line (such as the yellow line through the origin) has exactly one crossing point with the curve.
A function that associates to any of the four colored shapes its color.
The above diagram represents a function with domain 1, 2, 3, codomain A, B, C, D and set of ordered pairs (1,D), (2,C), (3,C). The image is C,D. However, this second diagram does not represent a function. One reason is that 2 is the first element in more than one ordered pair. In particular, (2, B) and (2, C) are both elements of the set of ordered pairs. Another reason, sufficient by itself, is that 3 is not the first element (input) for any ordered pair. A third reason, likewise, is that 4 is not the first element of any ordered pair.

In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number x to its square x. The output of a function f corresponding to an input x is denoted by f(x) (read "f of x"). In this example, if the input is −3, then the output is 9, and we may write f(−3) = 9. Likewise, if the input is 3, then the output is also 9, and we may write f(3) = 9. (The same output may be produced by more than one input, but each input gives only one output.) The input variable(s) are sometimes referred to as the argument(s) of the function.
