Answer 4

i just put them up

Answer 5

ooh..seen it sory

Answer 6

it's cool

Answer 7

Part A: Linear for option 1, because it increases at a constant rate, exponential for option 2 because it is multiplied by a rate each time.

Part B: Option 1: f(n) = 1000 +300n, because it starts at 1000 and increases 300 every year.
Option 2: f(n) = 1000*1.12^n, because it gets multiplied by 1.12 every time.

Part C: Option 1: f(20) = 1000+300*20 = 7000
Option 2: f(20) = 1000*1.12^20 = 9646.29

Option 2 is better.
