Mar 27, 2022 · Functions are even or odd depending on how the end behavior of the graphical representation looks. For example, \(y=x^2\) is considered an even function because the ends of the parabola both point in the same direction and the parabola is symmetric about the \(y\)−axis. \(y=x^3\) is considered an odd function for the opposite reason.
