Question

This is the graph of y=-x^2-4x-7. What is the range of this function?

Answer 1

Given the function:

`y=-x^2-4x-7`

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:

`y\leq-3`

ANSWER: A

`y\leq-3`
