Answer
(A) The curve is symmetric about y-axis as well as origin.
(B) The curve is not symmetric at all
(C) The curve is symmetric about y-axis only.
(D) The curve is symmetric about origin only
Work Step by Step
The curve is symmetric about y-axis, if $(x_1, y_1)$ lies on the curve, then, $(-x_1, y_1)$ also lies on the curve. The curve is symmetric about origin, if $(x_1,y_1)$ lies on the curve, then, $(-x_1, -y_1)$ also lies on the curve.
