Even and Odd Functions

Front

What is an even function?

Back

A function f(x) is called an even function if f(-x) = f(x) for all x in the domain of f. Graphically, even functions are symmetric about the y-axis.

What is an odd function?

Back

A function f(x) is called an odd function if f(-x) = -f(x) for all x in the domain of f. Graphically, odd functions are symmetric about the origin.

What does it mean if a function is neither even nor odd?

Back

A function is neither even nor odd if it does not satisfy the conditions for being even or odd. This means that f(-x) is not equal to f(x) or -f(x) for all x.
