Determine whether the following functions are even or odd or neither.

[Somminie]

So for this question

F(x)= x^3+2x

I was told to find whether this function is even, odd, or neither

I got that it was neither but the answer sheet my teacher provided us said that this function was odd. Did I do something wrong?

What are the relevant definitions?

 

[Harry_the_cat]

Does f(-x) = - f(x) ? Why do you come to the conclusion it is neither?

Does f(-x) = - f(x) ? Why do you come to the conclusion it is neither?

Your right! I forgot to check for -f(x).
