1.设给定实数集合X,若存在一对应法则∫,x∈X,彐唯一的实数 y∈R与之对应。则称∫是定义在X上的函数,记为:

In this example, the domain is the set fa,b, c, d, el and the range is the set Y= (1, 2, 3, 4, 5/. Related elements are joined by an arrow. This relation is a function because every element on the left is related to exactly one element on the right. In graph-theoretic
