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}

B. {-7,4,8}

Step-by-step 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):

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