3. Function 函数 A function from X to Y is a binary relation R that satisfies:1. For all x \in X, there exists y \in Y such that xRy.2. If y,z \in Y such that xRy and xRz, then y=z. 3.1 Notation 记法 We typically use f,g,h to represent functions ...
四、反函數(inverse function) 若有一函數 f 代表 X→Y,則其反函數 f⁻¹ 就是 Y→X,可以有反函數的函數稱為「可逆函數(invertible function)」,所有可逆函數必為雙射函數。 在下圖中,f(x) 與 f⁻¹(x) 互為反函數關係、g(x) 與 g⁻¹(x) 亦互為反函數關係。對於 f(x) 及 g⁻...
Function是一种特殊的relation,它满足一一对应的特性,即对于集合A中的每一个元素a,都有且仅有一个元素b与之相对应。一个function可以看作是一种输入和输出之间的关系,每一个输入都有唯一的输出。在数学中,function通常用f(x)来表示,其中x是输入,f(x)是输出。 3. Relation和Function的区别 了解了relation和func...
