Even and Odd Functions A function f is an even function if f(-x) =f(x) for all x in the domain of f. The graph of an even function is symmetric with respect to the y-axis. . A function fis an odd function if f(-x) = -f(x) for all x in the domain of f. The graph of an odd function is symmetric with respect to the origin. Example: For the given function f (a ) - 4x - 5x , find a) f(-ac) and b) - f(a ) Determine if the function is even, odd, or neither.
