Answer:
B
Step-by-step explanation:
The range of a data set is the y-coordinates of the ordered pairs.
So, we have the ordered pairs:
{(-2,1), (0,0), (3,-1), (-1,7), (5,7)}
So, the range will be (the bolded numbers):
{(-2,1), (0,0), (3,-1), (-1,7), (5,7)}
Thus, our answer is:
{-1, 0, 1, 7}
Note that the range should be in ascending order.
Also note that even though 7 appears twice, 7 is 7, so we only put one 7.
The answer is B.
