Practice makes perfect
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. We can see that the solutions are x=- 4 and x=1. This corresponds to option J.
