(a)
If the point ![\"(5,](\"http://latex.codecogs.com/gif.latex?%285%2C%203%29\")
is on the graph of an even function, then the point ![\"(-5,](\"http://latex.codecogs.com/gif.latex?%28-5%2C%203%29\")
also should present in the graph because even function is symmetric about the ![\"y-\"](\"http://latex.codecogs.com/gif.latex?y-\")
axis.
(b)
If the point is on the graph of an odd function, then the point ![\"(-5,](\"http://latex.codecogs.com/gif.latex?%28-5%2C%20-3%29\")
also should present in the graph because odd function is symmetric about the origin.
