B. Let N be the set of natural numbers, A = {1, 2, 3, 4, ...
1 1 1 ·}, B = { ¹ : 1 ≤ x ≤ 10, where x EN}.
(10) State explicitly the elements of the set B (write set B in set-roster notation).
(11) Write set A in set-builder notation (follow the format A = {x EX : P(x)}).
For items (12)-(14), Let the mapping F: N→A be defined as F(x) = ¹.
(12) Evaluate F (10)
(13) Evaluate 100 F (5) - 20.
.
(14) Is the mapping F a function? Why or why not?
