Inspecting the graph, we can say that
OC. No; because when the graph is folded along the x-axis, the parts above and below the x-axis do not coincide.
OA. Yes; because when the graph is folded along the y-axis, the parts to the left and right of the y-axis coincide.
When is a graph symmetric to the y-axis
A graph is symmetric with respect to the y-axis if it remains unchanged when reflected across the y-axis.
A figure is y-axis symmetric if, for every point (x, y) in the graph, the point (-x, y) is also part of the graph.
The graph attached shows symmetric on y-axis
