Answer: Option D: -8 ≤ y ≤ -3
Explanation:
The range of functions is the set of all the possible values of y.
you can see that the maximum value of y is y = -3, and the minimal value of y is y = -8 (those are the maximum/minimum values because of the dots in the line, that mean that the line ends/begins at those points)
Then the range is -8 ≤ y ≤ -3
The correct option is D
