Odd and even function

  1. Aug 19, 2007 #1
    f(x) is an even function if f(-x) = f(x) for any x in the domain of f.
    Now I say that f(x) = x^2 is defined on [-5,10]. Can I say f(x) is an even function?

    No, you can't.
    An odd or even function must be defined on a symmetric domain.
    But [-5,10] is not symmetric.

    Is f(8)= f(-8)?
