Step-by-step explanation:
The solution of a quadratic equation is simply when the graph crosses the x-axis. This is because at that point, the function will equal 0.
From the graph, we can see that the graph touches the x-axis at x=-4 and x=-3.
Therefore, our solutions for the graphed quadratic is x=-4 and x=-3.
And we're done!
