WebFeb 25, 2024 · How to find the Cardinal Number of a Set? 1. Find the cardinal number of the following set E = { x : x < 0, x ∈ N } Solution: x<0 means negative integers and they don’t fall under Natural Numbers. Therefore, the above set will not have any elements Cardinal Number of Set E is n (E) =0 2. Find the Cardinal Number of the Following Set WebLet X be a nonempty set. The characteristic function of a subset E of X is the function given by χ E(x) := n 1 if x ∈ E, 0 if x ∈ Ec. A function f from X to IR is said to be simple if its range f(X) is a finite set.
The set {x:x ∈ N and x^2 = 9} is - Toppr
Web例3 (1)已知集合A＝{x x2－3x0}，B＝{1，a}，且A∩B有4个子集，则实数a的取值范围是( ) A．(0,3) C．(0,1) 答案 B . 解析 因为A∩B有4个子集，所以A∩B中有2个不同的元素，所以a∈A，所以a2－3a0，解得0 (2)已知集合A＝{x x 2 答案 D . 解析 集合B＝{x x2－3x＋20}＝{x 1 WebAug 1, 2024 · It is the set of roots of the quadratic equation: $x^2−x−2=0$.
