Answer:
A) F(x) < 0 over the intervals (-∞, -0.7) and (0.76, 2.5)
Step-by-step explanation:
Given graph represents the function F(x).
If the graph of F(x) is below the x-axis then F(x)<0.
If the graph of F(x) is above the x-axis then F(x)>0.
The graph of F(x) intersect the x-axis at -0.7, 0.76 and 2.5.
From the given graph it is clear that
F(x)<0 over the interval (-∞,-0.7).
F(x)>0 over the interval (-0.7,0.76).
F(x)<0 over the interval (0.76,2.5).
F(x)>0 over the interval (2.5,∞).
Since F(x) < 0 over the intervals (-∞, -0.7) and (0.76, 2.5), therefore, the correct option is A.
