even function
[even function|even function] is a function whose graph is symmetric about the y-axis, meaning f(−x) = f(x).
Definition
even function is a function whose graph is symmetric about the y-axis, meaning f(−x) = f(x).
Mechanism
even function The graph of an even function is symmetrical about the y-axis, meaning f(−x) equals f(x). A function whose graph is symmetric about the y-axis is termed an even function.
Causes
even function The graph of an even function is symmetric about the y-axis. This symmetry indicates the function's relationship to the vertical axis.
