{{ printedBook.courseTrack.name }} {{ printedBook.name }} We want to use the given graph to determine the solutions of the related quadratic equation. The solutions of these equations are the $x-$coordinates of the points of intersection of the parabola and the $x-$axis. Recall that a quadratic equation can have two, one, or no solutions. Let's consider the graph.

This graph crosses the $x-$axis twice, so its related equation, $f(x)=0,$ has two solutions. We can see that those solutions are $x=-2$ and $x=5.$
