For Example 7 in the chapter: A = {1, 2, 3, 4, 5, 6} and R = {(x, y): y = x + 1}. The range of R is:
A{2, 3, 4, 5, 6}
B{1, 2, 3, 4, 5, 6}
C{1, 2, 3, 4, 5}
D{0, 1, 2, 3, 4, 5}
Answer & Solution
Correct answer: A. {2, 3, 4, 5, 6}
R = {(1,2),(2,3),(3,4),(4,5),(5,6)} — note (6,7) excluded since 7 ∉ A. Range = set of second coordinates = {2, 3, 4, 5, 6}. Note range ⊂ codomain {1,2,3,4,5,6}.
