Based on the information provided about the graph, we know that the graph intersects the x-axis at the points (2.5, 0) and (3, 0). This indicates that those x-values are solutions of the equation represented by the graph.
The solutions from the options you provided are:
- x = 2.5
- x = 3
The other options, x = -15, x = -3, and x = -2.5, do not appear to be solutions based on the intersections you described.
Thus, the correct solutions are:
- x=2.5
- x=3
