Question

Choose the relation with a range of {−6, −3, −2, 0, 5}.

A. R = {(5, 6), (0, 3), (−2, 5), (−3, 5), (−6, 8)}

B. R = {(−6, −3), (−2, −2), (0, 5)}

C. R = {(5, −3), (4, −6), (2, −2), (−2, 5) (−1, 0)}

D. R = {(5, 0), (−2, −2), (−3, −6)}

Answer 1

Range is the second element of each set of ordered pair.
I'll illustrate this with the first example, you check the other options
A)R = {(5, 6), (0, 3), (−2, 5), (−3, 5), (−6, 8)}
\[{(5, \underline 6), (0, \underline 3), (−2, \underline 5), (−3, \underline 5), (−6, \underline 8)} \]
Range={6, 3, 5, 5, 8}
Each element will only come once, and arranging in ascending order
Range={3, 5, 6, 8}
Do you understand this @davisgurl101 ?

Answer 2

no i dont under stand

Answer 3

Where do you have doubt?

Answer 4

i dont under stand any of it

Answer 5

Relation is defined as a mapping from set A too set B
so the range of relation is set B
suppose the mapping is (1, 2), (3, 4)
range here is 2, 4
do you get this?
