@soprano.h.d0816 here it is

Answer 2

Well. I am confusing myself on this one. Lol

Answer 3

I know right, but I just need help with part B and C because I have this Part A:
Neighborhood A f(x)=30∗0.2x

Neighborhood B (x)=45+3x

Answer 4

For part B, you'd plug in 5 for x

Answer 5

Yah but it would be like this?
f(x)=30(1.2)^5
30(2.4)
72
f(x)=45+36^5=288

Answer 6

Where did you get 1.2 from?

Answer 7

So, is not 1.2? is 0.2? because is increasing I think
