0. f(-2) for f(x) = -x^2 %2b 3
1. f(2) for f(x) = -2 -x
2. f(10) for f(x) = -2 - x
3. find x for f(x) = 10 when f(x) = 2x - 6
4. find x for f(x) = 8 when f(x) = 2x -6
5. f(12) for f(x) = -2(x %2b 2)
6. find x for f(x) = 20 when f(x) = -2(x %2b 2)
7. f(-2) for f(x) = x^2 %2b 3
8. f(2) for f(x) = x^2 %2b 3
9. f(2) for f(x) = 3x
10. find x for f(x) = 10 when f(x)= -2 - x
11. f(10) for f(x) = 2x - 6
12. f(-2) for f(x) = 3x
13. f(2) for f(x) = -x^2 %2b 3
14. f(-2) for f(x) = -2x-2
15. f(-2) for f(x) = -2 -x
