Question

Let A = [ 1 , 2 ) and B = ( 2 , 4 ] . The what is d ( A , B )​ explan ans plz​

Answer 1

Answer:

A = 1,2

B = 1,2 x 2 = 2,4

D = 1,2 x 4 = 4,8

Answer 2

d(A, B) = [1, 4]

Step-by-step explanation:

Given two bounds are

1. A = [1, 2) ⇒ A : 1 ≤ x < 2
2. B = (2, 4] ⇒ B : 2 < x ≤ 4

Clearly, for A, x is equal to or greater than 1 and less than 2. For B, x is greater than 2 and equal to or less than 4.

Since we have to find d(A, B), that is the distance between A and B, combining A and B, we get

d(A, B) : x is equal to or greater than 1 and equal to or less than 4, that is

d(A, B) : 1 ≤ x ≤ 4 ⇒ d(A, B) = [1, 4]

Note:

The symbols ( ) and [ ] refer to closed but not equal and close and equal respectively.
