Is the given function even, odd, or neither?

To determine if the function is even, odd, or neither, we can evaluate . Replacing with gives us:

Now, notice that:

Since , this means the function is odd.

As a fun nugget, the concept of even and odd functions was introduced in the 17th century and is key in various fields such as calculus and physics, especially when discussing symmetry. Odd functions, like this one, have rotational symmetry about the origin, which can be pretty neat when grappling with graphs!

For practical application, odd functions often help in simplifying integrals over symmetric intervals like , where the integral of an odd function will always result in zero. So, knowing whether a function is odd can save time and effort in calculations!
