Its an even function. For odd function, its a reflection with respect to origin. Means you take reflection with respect to both X and Y. Like sine function. You can just look at the plot and tell if its an even or odd function. | |

Could you explain just a little bit more what this means, perhaps giving examples of functions that you consider to be even function and odd respectively? I get the feeling that maybe your definition allows a function to be both even and odd. Is that so? | |
