The graph plots x-values on the horizontal axis. It is the horizontal line labeled "x" at the right side of the graph. Values near zero (small values) are near the y-axis, which is the vertical line labeled "y" at the top. Negative x-values are on the left side of the y-axis.
To answer the question, find small x-values (near the y-axis on the left side) and find the corresponding points on the plot of F(x), the blue curve. You will see they are large negative y-values (well below the x-axis). This observation guides you to select ...
B. F(x) is a very large negative number.
