Given the relation R = { (−2, 3), (a, 4), (1, 9), (0, 7) }. Which replacement for a makes this relation a function?
−2
4
1
0
The relation defined by the set of ordered pairs { (0, 2), (−2 ,2), (1, 4), (4, 1), (0, −1) } is not a function. Which of the ordered pairs listed below, if omitted from this relation, will make the resulting set a function?
(0, −1)
(1, 4)
(−2,−2)
(4, 1)
The domain of this function is
{ (3,2), (−2 ,5), (-3, 1), (2, 1) }
-3, -2, 2
1, 2, 5
-3, -2, 2, 3
1, 1, 2, 5
The range of this function is
{ (3,2), (−2 ,5), (-3, 1), (2, 1) }
-3, -2, 2, 3
-3, -2, 2
1, 2, 5
-2, 2, 5, 1
A mapping is shown in the diagram below.
This mapping is
not a function, because Feb has two outputs, 28 and 29
not a function, because two inputs, Jan and Mar, result in the output 31
a function, because two inputs, Jan and Mar, result in the output
a function, because Feb has two outputs, 28 and 29
