Answers:
0. f(x) = 12(0.92)^x
1. f(x) = 88(1.02)^x
2. f(x) = 12( 0.12)^x
3. f(x)= 12(1.02)^x
4. f(x) = 88 (1.2)^x
5. f(x) = 8 (0.92)^x
6. f(x) = 12 (2) ^x
7. f(x) = 8(0.08)^x
8. f(x) = 88(1.12)^x
9. f(x) = 2 (1.12)^x
10. f(x) = 88(1.2)^x
11. f(x) = 12 (1/2) ^x
12. f(x) = 2(0.88)^x
13. f(x) = 1.12(2)^x
14. f(x) = 12 (1.88)^x
15. f(x) = 8 (2)^x
