So the answers are:
x-axis only
y-axis only
x-axis, y-axis
x-axis, y-axis and origin.

Is it the last one. I'm pretty sure it's the last one.
I know it has symmetry on the x-axis but because it looks symmetrical at the origin, is it the last one?

Could you just look at the link and double check if it's only the x-axis or if it's x-axis, y-axis, and origin?
