The solutions to the equation are the x-coordinates of the points of intersection of the graph and the x-axis.
J
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 given graph.
We can see that these solutions are x=- 7 and x=1, which corresponds to option J.
