Answer:
11. odd, 12. slope = 2 and the line rises.
Explanation:
11. To determine if the function is odd, even, neither, you have to plug in -x in the function and simplify.If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even. If you end up with the exact opposite of what you started with (that is, if f (–x) = –f (x), so all of the signs are switched), then the function is odd. In all other cases, the function is "neither even nor odd".
12. y2 - y1 / x2 - x1
1-9/-2-2 = 2
