Homework 2. Homework 3. Let d be a metric on X. Determine all constants k such that the following is a metric on X (a) kd. (b) d + k. (Product of metric spaces) The Cartesian product X = X₁ x X₂ of two metric spaces (X₁, d₁) and (X2. d₂) can be made into a metric space (X, d) in many ways. For instance, show that a metric d is defined by d(x, y) = d₁(₁.₁) + d₂(x2, 2), where x = (1, 2), y = (y₁.92).
