Continuous proofs

  1. Oct 31, 2007 #1
    say function f is continuous on (-[tex]\infty[/tex],[tex]\infty[/tex]). show that f can be written as f = g + h, where g is an even function and h is an odd function.

    help pleaseee!

    If f(x)=g(x)+h(x) where g is even and h is odd, then what is f(-x)?

    yeah, use those properties to help you construct your g and h out of f's

    f(-x) = g(-x) + h(-x)
    f(-x) = g(x) - h(x)
    = g(x) + (-h(x))

    is that it??

    Ok, then what is f(x)+f(-x)? Then what is g(x), and finally what is h(x)?
