Question

Which set represents the range of the function shown?

{(-1, 5), (2, 8), (5, 3), (13, -4)}
A. {-1, 2, 5, 13}
B. {-4, 3, 5, 8}
C. {(5, -1),(8, 2),(3, 5),(-4, 13)}
D. {-4, -1, 2, 3, 5, 5, 8, 13}

Answer 1

The range of a function given by the set {(-1, 5), (2, 8), (5, 3), (13, -4)} is the set of y-values, which is option B. {-4, 3, 5, 8}.

Step-by-step explanation:

The student is asking about the range of a function given by a set of ordered pairs. The range of a function is the set of all possible output values (y-values). Looking at the given set of ordered pairs {(-1, 5), (2, 8), (5, 3), (13, -4)}, the y-values are 5, 8, 3, and -4. Thus, the range of the function is the set of these y-values.

Answer: B. {-4, 3, 5, 8}
