Question

The graph of $y=-x^2$ is

• A. Symmetric about the origin
• B. All of the above
• C. symmetric about the $y-$axis
• D. symmetric about the $x-$axis

Answer 1

The correct option is C symmetric about the $y-$axis

Graph of $y=-x^2$ is symmetric about $y-$axis. For negative $x$ values, the $y$ values are exacly same as the $y$ values for the corresponding positive $x$ values.
So $y-$axis divides the curve into two equal parts which are mirror images of each other.
