1. The problem asks to identify what the green dots on the graph represent. 2. The green dots are located where the parabolas intersect the x-axis. 3. Points where a parabola crosses the x-axis are called the roots or x-intercepts. 4. The axis of symmetry is a vertical line that divides the parabola into two mirror images, not points. 5. The vertex is the highest or lowest point on the parabola, not the points on the x-axis. 6. The parabola is the curve itself, not specific points. Therefore, the green dots are the roots or x-intercepts of the parabolas.
