Answer:
F(x)>0 over the interval [tex](-\infty,-4)[/tex]
Step-by-step explanation:
If you pay close attention to the intervals given in the options, you can see that they are talking about the region to the left of either x=-3 or x=-4. The only statements that makes sense is that:
F(x)>0 over the interval [tex](-\infty,-4)[/tex]
When they say F(x)>0, they mean that the graph is above the x-axis and that will only happen when the x-values that are to the left of x=-4, therefore the answer would be:
F(x)>0 over the interval [tex](-\infty,-4)[/tex]
