In mathematics, functions can be classified as even, odd, or neither based on their symmetry properties. \#\#\# Even Functions A function \\( f(x) \\) is called an **even function** if it satisfies the following condition for all \\( x \\) in its domain: \\\[ f(-x) = f(x) \\\] This means that the function has symmetry about the y-axis.
