Which of the following relations represents a function?
A. {(1, 1), (1, 2), (1, 3)}
B. {(1, 1), (2, 1), (3, 1)}
C. {(1, 1), (2, 2), (3, 3)}
D. Both B and C.
Answer:D
Which of the following relations represents a function?
A. {(1, 1), (1, 2), (1, 3)} B. {(1, 1), (2, 1), (3, 1)} C. {(1, 1), (2, 2), (3, 3)} D. Both B and C.
Explanation: Both B and C are functions. For each input in the relations {(1, 1), (2, 1), (3, 1)} and {(1, 1), (2, 2), (3, 3)}, there is only one output. Therefore, these relations are functions. You answered this question...
