What is the range of the given function?

| [tex]$x$[/tex] | [tex]$y$[/tex] |
|-----|-----|
| -5 | 9 |
| 1 | 0 |
| 4 | -7 |
| 6 | -1 |

A. [tex]$\{x \mid x=-5,1,4,6\}$[/tex]
B. [tex]$\{y \mid y=-7,-1,0,9\}$[/tex]
C. [tex]$\{x \mid x=-7,-5,-1,0,1,4,6,9\}$[/tex]
D. [tex]$\{y \mid y=-7,-5,-1,0,1,4,6,9\}$[/tex]



Answer :

To find the range of the given function, we need to examine the y-values corresponding to each coordinate pair [tex]\((x, y)\)[/tex] provided.

The given coordinates are:
- [tex]\((-5, 9)\)[/tex]
- [tex]\((1, 0)\)[/tex]
- [tex]\((4, -7)\)[/tex]
- [tex]\((6, -1)\)[/tex]

Step-by-step, let's list the y-values:
- For coordinate [tex]\((-5, 9)\)[/tex], the y-value is [tex]\(9\)[/tex].
- For coordinate [tex]\((1, 0)\)[/tex], the y-value is [tex]\(0\)[/tex].
- For coordinate [tex]\((4, -7)\)[/tex], the y-value is [tex]\(-7\)[/tex].
- For coordinate [tex]\((6, -1)\)[/tex], the y-value is [tex]\(-1\)[/tex].

Now, we collate all the y-values:
[tex]\[ 9, 0, -7, -1 \][/tex]

After listing these y-values, we remove any duplicates (though none exist in this case) and sort them in ascending order:
[tex]\[ -7, -1, 0, 9 \][/tex]

Thus, the range of the function, which is the set of all distinct y-values from the given points, is:
[tex]\[ \{ y \mid y = -7, -1, 0, 9 \} \][/tex]

Therefore, the correct option for the range of the given function is:
[tex]\[ \{ y \mid y = -7, -1, 0, 9 \} \][/tex]
