Given the function:

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

$y\leq-3$
