Web30. jún 2011 · This kind of symmetry is called origin symmetry. An odd function either passes through the origin (0, 0) or is reflected through the origin. An example of an odd function is f(x) = x 3 − 9x. The above odd function is equivalent to: f(x) = x(x + 3) (x − 3) Note if we reflect the graph in the x -axis, then the y -axis, we get the same graph.
