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.
Add those ingredients. Or add the question you need help with
To divide 343 by 9, you will use the division algorithm.
The reason is because 343 is not divisible evenly by nine.
You know this because the sum of the digits, 3+4+3 or 10, is not evenly divisible by 9.
Therefore, 343 is not evenly divisible by 9.
2x + 5 - x simplified would be...
x + 5
