Even Function Properties: An even function satisfies the condition f(x) = f(-x).
 Odd Function Properties: An odd function satisfies the condition f(x) = -f(-x).
 Sum of Even Functions: The sum of even functions is always an even function.
 Product of Even and Odd Functions:
 Even * Even = Even
 Even * Odd = Odd
 Odd * Odd = Even
 Sum of Even and Odd Functions: The sum of an even and an odd function is neither even nor odd, unless the terms cancel out.
