3. Prove that the two open intervals (2, 5) = {x ∈ R: 2 < x < 5} and (3, 7) = {x ∈ R: 3 < x < 7} have the same cardinality by, finding a bijection between them (and proving that it is a bijection).
Sri K.
Consider two sets A and B and a function f: A to B between them. Find a bijection from the half-open interval [0,1) to the closed interval [0,1] and show that it is bijective, or else show why it is impossible.
