Solve number 1

Transcribed Image Text:1. Let M be a set with two members a and b. Define the function
D: M X M as follows: D(a, a) = D(b, b) 0, D (a, b) D(b, a) = = r
where r is a positive real number. Prove that (M, D) is a metric space.

2. Let M be a set with three elements: a, b and c. Define D: M X M
as follows: D(x,x) = 0 for all x E M; D(x, y) = D(y, x) is a positive
real number for xy. Say D(a, b) = r, D(a, c) = s, D(b, c) = t with
r≤st. Prove that (M, D) is a metric space if and only if t ≤r + s.
