Question

What are the domain and range of the relation {(-4,2), (0,1), (0,5), (8,10)}?
A. Domain: {2,1,5,10}; Range: {-4,0,8}
B. Domain: {-4,0,5,10}; Range: {2,1,8}
C. Domain: {-4,0,8}; Range: {2,1,5,10}
D. Domain: {-4,2,0,1,5,8,10}; Range: {-4,2,0,1,5,8,10}
Please help ;)

Answer 1

Domain should contain the first number (x) of all the ordered pairs.
Range should contain the second number (y) of all the ordered pairs.
There should be no repetition in either the domain or range.
Example:
the domain of {(2,4),(3,6),(4,7),(5,6)} is {2,3,4,5}, and the range is {4,6,7} after eliminating the repetition of 6.
