Question

What is the range of the given function?
((-2, 0), (4-3). (2-9), (0.5) (-5, 7))}

Answer 1

Range = {-9, -3, 0, 5, 7}

Explanation:

The range of a function is the set of all output values that the function can take

The input and output values of the function are (-2, 0), (4-3). (2-9), (0.5) (-5, 7))

First number in parenthesis is input to function

Second number in parenthesis is input to function

So just collect the second values of each of the entries and express them in set notation, eliminating duplicate values.

The set of output values = {0, -3, -9, 5, 7}

We re-arrange them in order from least to greatest and get

Range = {-9, -3, 0, 5, 7}
