Please do the even numbers like 2, 9, 10, 12. Please do it on paper bc it's really hard to understand when is written on here. Also, please show step by step how you got that answer. Also, I'm going to be posting some examples and it would be really helpful if they can be answered in the same format so I can understand more easily.

List your answers in terms of ordered pairs. Then sketch a graph of the function. 1. f(x) = x2 - 4x+5 2. f(x) = x2 - 6x - 3 3. f(x) = 5+x-x2 4. f(x) = 2 - 3x - 2x2 5. f (x) = 1+ 6x+ 3x2 6. f(x) = 0.5x2 - 2x - 11 7. f(x) = x3 - x2 - x+2 8. f(x) = x3+ 2x2 - 2x+5 9. f(x) = x3 - 3x+6 10. f (x) = x3 - 3x2 11. f(x) = 2x3 12. f(x) = 1 -x3 13. f(x) = 0.02x2 + 1.3x + 2.31 14. f(x) = -0.03x2 + 1.8x - 3.45 15. f(x) = x4- 2x3 16. f(x) = x4-8x2+3
