Question

The set of ordered pairs (–1, 8), (0, 3), (1, –2), and (2, –7) represent a function. What is the range of the function?

Answer 1

in an x,y ordered pair set, the range is always the value of "y", therefore


`\bf \{(-1,\stackrel{\downarrow }{8}),(0,\stackrel{\downarrow }{3}),(1,\stackrel{\downarrow }{-2}),(2,\stackrel{\downarrow }{-7})\}\impliedby \textit{that's the range}`

Answer 2

Answer: The required range is {-7, -2, 3, 8}.

Step-by-step explanation: Given that the set of ordered pairs (–1, 8), (0, 3), (1, –2) and (2, –7) represent a function.

We are to find the range of the function.

We know that

the range of a function in the form of ordered pairs is the set of all the second elements.

Therefore, the range of the given function is

R = {-7, -2, 3, 8}.

Thus, the required range is {-7, -2, 3, 8}.
