Question

What is the range of the function represented by these ordered pairs?

Answer 1

B

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.
