<reasoning>

Identify the meaning of solutions on a graph

Using the x-intercept and Coordinate Plane knowledge points
\[
\text{Solutions of } f(x) = 0 \text{ correspond to the } x\text{-intercepts of the graph } y = f(x).
\]

Locate the x-intercepts from the graph

Using the Coordinate Plane knowledge point
\[
\text{The parabola crosses the } x\text{-axis at } x = -3 \text{ and } x = -1.
\]

Order the solutions

The problem requires entering the smallest solution first:
\[
-3 < -1 \implies x = -3, -1
\]
</reasoning>

<answer>
Use the graph to find the solutions of this quadratic function.

\(x =\) <blank>-3</blank>, <blank>-1</blank>

Enter the smallest solution first.
