Question

What is the range of the given function?

{(–2, 0), (–4, –3), (2, –9), (0, 5), (–5, 7)}

{x | x = –5, –4, –2, 0, 2}
{y | y = –9, –3, 0, 5, 7}
{x | x = –9, –5, –4, –3, –2, 0, 2, 5, 7}
{y | y = –9, –5, –4, –3, –2, 0, 2, 5, 7}

Answer 1

The range of a function is the set of all possible output values (y-values) that the function can produce. Given the set of ordered pairs:

{(–2, 0), (–4, –3), (2, –9), (0, 5), (–5, 7)}

we extract the y-values from each pair:

0, –3, –9, 5, 7

The range of the function is the set of these y-values. Therefore, the correct answer is:

**{y | y = –9, –3, 0, 5, 7}**
