What is the range of the given function?

[tex]\[ \{(-2, 0), (-4, -3), (2, -9), (0, 5), (-5, 7)\} \][/tex]

A. \(\{x \mid x=-5, -4, -2, 0, 2\}\)

B. \(\{y \mid y=-9, -3, 0, 5, 7\}\)

C. \(\{x \mid x=-9, -5, -4, -3, -2, 0, 2, 5, 7\}\)

D. [tex]\(\{y \mid y=-9, -5, -4, -3, -2, 0, 2, 5, 7\}\)[/tex]



Answer :

Let's find the range of the given function with the set of points:
[tex]\[ \{(-2,0),(-4,-3),(2,-9),(0,5),(-5,7)\} \][/tex]

The range of a function consists of all possible values that the dependent variable \( y \) can take. To find these values, we'll look at the \( y \)-coordinates of the provided points.

First, we list all the given points:
1. \((-2, 0)\)
2. \((-4, -3)\)
3. \((2, -9)\)
4. \((0, 5)\)
5. \((-5, 7)\)

Next, extract all the \( y \)-coordinates from these points:
- \( y = 0 \)
- \( y = -3 \)
- \( y = -9 \)
- \( y = 5 \)
- \( y = 7 \)

Now, let's arrange these \( y \)-values in ascending order and remove any duplicates:

[tex]\[ \{ -9, -3, 0, 5, 7 \} \][/tex]

Therefore, the range of the given function is:
[tex]\[ \{ y \mid y = -9, -3, 0, 5, 7 \} \][/tex]

Among the provided options, the correct one describing the range of the function is:
[tex]\[ \{ y \mid y = -9, -3, 0, 5, 7 \} \][/tex]

So, the correct answer is:
[tex]\[ \{ y \mid y = -9, -3, 0, 5, 7 \} \][/tex]
