the answer to The set of ordered pairs (–1, 8), (0, 3), (1, –2), and (2, –7) represent a function. What is the range of the function? the answer is {y: y = –7, –2, 3, 8}
awnser is B
you need to review the definition of range
Given a set or ordered pairs (x,y), the range is the set of all the y-values.
As usual, they have listed them in increasing order, though that's not a strict requirement -- it just makes it easier to visualize their values.
The set of ordered pairs (–1, 8), (0, 3), (1, –2), and (2, –7) represent a function. What is the range of the function?
The set of ordered pairs (–1, 8), (0, 3), (1, –2), and (2, –7) represent a function. What is the range of the function?
Determine the domain and range of the given function.
The domain is
.
The range is
To find the range of the given function, we need to determine all possible y-values or outputs for the function.
The given set of ordered pairs represents the input and output values of the function. So, we look at the y-values in each pair to determine the range.
The set of y-values is {-7, -2, 3, 8}. Therefore, the range of the function is the set of these y-values.
Range = { -7, -2, 3, 8 }
Hence, the answer is {y: y = -7, -2, 3, 8}.
