A. Even
B. Neither
C. Odd

Are these correct?

One of those is correct.

Which one would that be?

Thanks!

You tell us. Then we can help.
Show all your work. Why did you answer the way you did?

Hint: $\sin(x)$ is odd; $\cos(x)$ is even; and $|x|$ is even.

5. ## Re: Which of the following functions are odd, even or neither?

So I redid my calculations. Are they correct now?

a) Odd
b) Even
c) Odd

Correct. But was that a guess?
You did not show any work!

Presumably your professor is going to want you to demonstrate that for the even functions you have $f(-x)=f(x)$ and for the odd functions $f(-x)=-f(x)$.

It wasn't a guess. I did the work in my notebook but I was just too lazy to post it. Thanks though!
