19. Carter went bowling. He recorded his score before his first turn and after each of his 10 turns
using the ordered pairs shown below. In each ordered pair, the x-coordinate represents the
number of turns he has taken and the y-coordinate represents his total score.
(0, 0) (1, 9) (2, 16) (3, 30) (4, 34) (5, 64) (6, 86) (7, 105) (8, 114) (9, 120) (10, 144)
What is the domain of Carter’s set of ordered pairs?
(A) {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
(B) {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
(C) {9, 16, 30, 34, 64, 86, 105, 114, 120, 144}
(D) {0, 9, 16, 30, 34, 64, 86, 105, 114, 120, 144}
