Question

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

(-2, 8), (0, -7), (3,4), (4,-7)
A. {-2,3,4}
B. {-7,4,8}
C. {-2, 0, 3, 4}
D. {-7,-4,4,8}

Answer 1

B. {-7,4,8}

Explanation:

In a function, the domain are the x values and the range are the y values.

In the function (-2, 8), (0, -7), (3,4), and (4,-7):

• The range, or y values, are -7, 8, and 4.

B would be the correct answer, since all the y values are listed without any x values.
