Answer:
Step-by-step explanation:
Given sets:
- a. {(1, 0), (2, 1), (2, 3)} ⇒ x- value repeated twice (2)
- b. {(1, 3), (1, 4), (1, 5)} ⇒ x- value repeated three times (1)
- c. {(1, 5), (2, 5), (3, 5)} ⇒ x- values are unique
- d. {(3, 1), (2, 2), (3, 3)} ⇒ x- values repeated twice (3)
- e. {(3, 2), (5, 1), (4, 0)} ⇒ x- values are unique
The sets c and e represent a function. The others have repeated x- values.
