Question 50755: Determine whether the relation is a function. If it is a function, state its domain and range.
{(–2, 3), (0, 10), (1, 3), (4, 8)}
a. Domain: {3, 10, 8}; Range: {–2, 0, 1, 4}
b. Domain: {–2, 0, 1, 4}; Range: {3, 10, 8}
c. Domain: {–2, 0, 1, 4}; Range: 7
d. The relation is not a function.
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! "b" because the domain is the set of 1st elements in the ordered pairs
and range is the set of 2nd elements in the orderd pairs, and each
1st element is paired with only one 2nd element.
Cheers,
