Give the range of the relation. (18, 4) (11, -3), (2, -2), (2, 0), (6, 2)
a. range: 11, 6, 2, 18
b. range: -3, -2, 2, 4
c. range: 11, 6, 0, 2, 18
d. range: -3, -2, 0, 2, 4
we know that
the range are the possible values of y in the data set
so
In this problem
range 4,-3,-2,0,2
therefore
the answer is the option d
Example
If you have
(3,1), (2,8), (7,3), (5,0)
the range are the values of y
so
the value of y is the second coordinate in each ordered pair
(3,1) ------> y-coordinate is 1
(2,8)-----> 8
(7,3) ----> 3
(5,0) ----> 0
therefore
the range is 1,8,3,0
order
Range (0,1,3,8)
