You can put this solution on YOUR website!
f(x)=[1/(x^4+3x^3)] even or odd?
Check:
-f(-x) = -1/[(-x)^4 + 3(-x)^3]
= -1/[x^4 - 3x^3
= 1/[-x^4+3x^3]
So f(x) does not equal -f(-x); so f is not odd
-----------------------------
Is it even?
Check:
f(-x) = [1/[(-x^)^4 + 3(-x)^3]]
=[1/[x^4 - 3x^3]]
So f(x) does not equal f(-x); so f is not even
