Answer
To find the solutions to the equation x2+x−6=0, we need to identify where the graph intersects the x-axis. The x-intercepts occur where y=0. According to the provided graph, the function intersects the x-axis at two points.
Step 2
Identify the x-values of the intercepts

Answer
From the graph, we can observe that the x-intercepts are approximately at x=−3 and x=2. Thus, the values of x that satisfy the equation are:
