Message text written by INTERNET:email@example.com > Topic of conversation in the math office today: Is it possible for a function or relation to be both symmetric to the y axis and to the origin but not to the x-axis? <
It has to be one symmetry or all 3, but any pair alone is impossible.
=3D=3D>The only thing I could think of was 3/4 of a circle. This has none of the above symmetries.
