See graph and explanation.
Explanation:
Upon changing x to
If f( - x ) = - f ( x ), the graph changes as mirror image with respect
to x-axis and the function is an odd function. Here, the combined
graph of both is symmetrical about x-axis. Example: sin x.
See separate graphs..
Graph of
graph{y + sin x = 0}
Graph of
graph{y - sin x = 0}
Combined graph of
graph{y^2 - (sin x)^2 = 0}
If f( - x ) = f ( x ), the graph does not change and the function i an
even function. Example
symmetrical about y-axis.
