It's the third one. It is the correct option.
5. y = -3 x - 8
6. y = - 1/2 x + 1
FG = FE
3n - 4 = n + 8
2n = 12
n = 6
FG = 3(6) - 4
FG = 18 - 4
FG = 14
answer
14
Answer:
From -2<x<-1, the function F(X) is increasing. (B)
Really, it increases all from around -2.5<x<0.5
C is also the second answer, as it increases til around 2.5
It is decreasing from -4<x<-3. But increases right after. It then starts to slow down around x = 1 and go down again.
Which means (B) is your answer.
If you want to get fancy, its a polynomial and if you take the derivative for instantaneous rate, you will see f prime is increasing if you make an example function.
It is no answer, because when you get 12x + 48 = 48 + 12x, they cancel each other out.
