if f isn't even function, that means it has y axis symmetry. So the Y axis is like a fold line. You could match the function up if you folded it along that line. Therefore, the other side of the function must be something like this. Now, if F is odd, that means it has origin symmetry where if you turned it 180 degrees, it would look like it already looks. So in order to do that, we need opposite X values to have opposite Why values and we're going to get something like this.
