Question

Choose the relation with a domain of {−4, 0, 1}.

R = {(3, 2), (1, 8), (1, 2), (0, −5), (−4, 4), (3, 5)}

R = {(−4, −2), (0, 0), (1, 3), (−4, −2), (1, 3)}

R = {(2, 3), (8, 1), (2, 1), (−5, 0), (4, −4), (5, −2)}

R = {(3, 1), (0, 0), (−2, −4), (3, 1), (−2, −4)}

Answer 1

Relation is a way to establish a corespondens between two sets of elements. What you obtain are the ordered pairs {a,b} where a belongs to the first set (called domain) and b belongs to the second set (called codomain). With this you should be able to answer the question yourself....

Answer 2

i dont get it

Answer 3

your 4 choices are 4 sets of ordered pairs (a,b), where the first element , a, have to belong to the domain {−4, 0, 1}.

Answer 4

got it?

Answer 5

R = {(−4, −2), (0, 0), (1, 3), (−4, −2), (1, 3)}
this is the answer
