Problem:
Determine the range of the function given the set of ordered pairs:
NO. 2). {(1, 3), (2, 4), (3, 5), (4, 6)}
a. {0, 1, 2, 3, 4}
b. {0, 1, 2, 3, 4}
c. {2, 3, 4, 5, 6}
d. {2, 3, 4, 5, 6}
Answer:
Among the given choices above, the correct is not there but the correct answer is {3, 4, 5, 6}.
Explanation:
The correct answer is {3, 4, 5, 6} because it’s all the second elements or y on the given ordered pairs.
Additional information:
1. The first elements or x on the given ordered pairs is called domain.
Example ordered pairs:
{(2, 6), (3, 7), (4, 8), (5, 9)}
The domain there are {2, 3, 4, 5}.
2. The second elements or y on the given ordered pairs is called range.
Example ordered pairs:
{(2, 6), (3, 7), (4, 8), (5, 9)}
The range there are {6, 7, 8, 9}.
