Note: A function can be neither even nor odd if it does not exhibit either symmetry. For example, f(x)=2x f ( x ) = 2 x is neither even nor odd. Also, the only function that is both even and odd is the constant function f(x)=0 f ( x ) = 0 . Is 2 AP classes too much? is 2 ap classes enough junior year.

What are the 4 odd functions?

Odd Functions: The identity function, the cubing function, the reciprocal function, the sine function.

How can you tell if a function is odd?

If you end up with the exact opposite of what you started with (that is, if f (–x) = –f (x), so all of the signs are switched), then the function is odd.
