Hot
F(x) < 0 over the interval (-00, 4)
F(x) < 0 over the interval (-0, -3)
F(x) > 0 over the interval (-00, -3)
F(x) > 0 over the interval (-0, -4)

Answer 1

Answer: D, F(x) > 0 over the interval (–∞, –4)

Explanation:

Answer 2

D.F(x) >0 over the interval (
`-\infty,-4)`

Explanation:

We have to find the true statement about graphed function.

A.F(x) <0 over the interval (
`-\infty,4`)

It is not true because in given graph the value of F(x) < 0 in interval (
`-4,\infty,)` and F(x)> 0 in interval (
`-\infty,-4)`.

B.F(x)<0 over the interval (
`-\infty,-3)`

It is not true because F(x)> 0 in interval (
`-\infty,-4)`.

C.F(x) >0 over the interval
`(-\infty,-3)`

It is not true because F(x) < 0 when -4<x<-3

D.F(x) >0 over the interval (
`-\infty,-4)`

It is true because F(x) >0 in interval
`(-\infty,-4)`

Hence, option D is true.
