(a) the domain and range
(b) the intercepts, if any
(c) any symmetry with respect to the x-axis, y-axis, or the origin

Determine if the graph represents a function
\[
\text{Every vertical line intersects the graph at most once} \implies \text{It is a function.}
\]
Find the domain and range
\[
\]
Find the intercepts and symmetry
\[
\]
</reasoning>
<answer>
Question 1
The graph represents a function because it passes the vertical-line test.
Question 2
The domain is \([-5, 0]\) and the range is \([-3, 2]\).
Question 3
The x-intercept is \((-4, 0)\) and the y-intercept is \((0, -3)\).
Question 4
The graph has no symmetry with respect to the x-axis, y-axis, or the origin.
