The graph described has an open point at 1 with a solid line extending to the right, indicating that x is greater than 1 (\(x > 1\)). It also has an open point at -3 with a solid line extending to the left, indicating that x is less than -3 (\(x < -3\)).
Therefore, the solution set represented on the graph is:
x < -3 or x > 1
So, the correct response is:
x < -3 or x > 1.
