Answer:
Step-by-step explanation:
A function is odd if f(-x) = -f(x)
A function is even if f(-x) = f(x)
And neither if neither are true.
In this case if we plugged in a negative x here
f(-x) = (-x)^3 - 11(-x)
f(-x) = -x^3 + 11
Therefore, this function is odd because if we pulled out a negative one again we would get back the original function. Or in other words f(-x) = -f(x) for f(x) = x^3 - 11x
