## anonymous one year ago Determine algebraically whether the function is even, odd, or neither even nor odd. f(x) = -9 x3 + 8x

1. anonymous

both exponents are ...

2. anonymous

odd

3. anonymous

bingo

4. tkhunny

That is not an "algebraic" solution.

5. anonymous

so wait you dont't have to do that long algebraic stuff?

6. anonymous

on the other hand, that is not what your math teacher wants you to say

7. anonymous

haha true thats what I thought but she doesnt need to see my work lol

8. anonymous

yeah your math teacher wants you to compute $f(-x)$ and show that it is $$-f(x)$$

9. anonymous

$f(-x)=-9(-x)^3+8(-x)=\text{ some algebra}=-(-9x^3+8x)=-f(x)$

10. anonymous

yeah haha I like the easy way but thanks!
