For the first one the answer is y=-1x+6 which means x=-1 and y=6
step 2 would be 10
step 4 would be 10x-x = 9x =7
x = 7/9
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.
4.2 because it has a box around the corner that makes it whole
