what is the range of this relation? (-8, 6) (6, 1) (7, -5) (-7, -3) (7, -3) {-7, -3, 1, 6} {-3, 1, 6, 7} {-8, -7, 6, 7} {-5, -3, 1, 6}
Answer
Explanation:
Step1: Recall range definition
The range of a relation is the set of all second - elements of the ordered pairs.
Step2: Identify second - elements
The ordered pairs are (-8, 6), (6, 1), (7, -5), (-7, -3), (7, -3). The second - elements are 6, 1, -5, -3, -3.
Step3: Form the range set
Removing duplicates, the range set is {-5, -3, 1, 6}.
Answer:
{-5, -3, 1, 6}
