Given the function:
[tex]y=-x^2-4x-7[/tex]
Let's find the range of the function using the graph.
The range of a function is the set of all possible values of y in the function. The range is also called the output.
The range is represented on the vertical axis of the graph.
From the graph shown, we can see the y-values start from the point -3 and the parabola goes down.
This means the range of the function is all values of y less than or equal to -3.
Thus, the range of the function is:
[tex]y\leq-3[/tex]
ANSWER: A
[tex]y\leq-3[/tex]
