Question

2. In the discrete metric space (x, d), the metric d'
is defined by
(A) d(x, y)=0, x=y&l if x # y
(B) d(x, y)=1, x = y & 0 if x #y
(C) d(x, y)=0,x,y
(D) d(x, y)=1, +(x, y)​

Answer 1

In the discrete metric space (x, d), the metric d'

is defined by

(A) d(x, y)=0, x=y&l if x # y

(B) d(x, y)=1, x = y & 0 if x #y

(C) d(x, y)=0,x,y

(D) d(x, y)=1, +(x, y)

• D(x,y)=0X, Y
