    Which of the following functions are odd, even or neither?



    This is what I got but I would like to be sure before I submit the work to my professor.

    A. Even
    B. Neither
    C. Odd

    Are these correct?

    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.

    Correct. But was that a guess?

    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!
