If a function is an even function, then it is symmetric with respect to the y - axis.

If a function is an odd function, then it is symmetric with respect to the x - axis.

(a)

The point is and function is even.

Since the function is an even function, symmetric point is .

(b)

The point is and function is odd.

Since the function is an odd function, symmetric point is .

(a) The second point is .

(b) The second point is .
