CALCULUS Understanding Its Concepts and Methods

Even and odd functions

An odd function
is a function *f*(*x*)
that satisfies *f*(-*x*) =
-*f*(*x*).

An even
function is a function *f*(*x*)
that satisfies *f*(-*x*) = *f*(*x*).

Geometrically, the graph of an even
function is symmetric with respect to the -axis,
while the graph of an odd function is symmetric with respect to
the origin.
