To determine if a curve is a function, we apply the vertical line test. A curve represents a function if any vertical line drawn through the graph intersects it at most once.
Since you mentioned that the curve intersects at (0,0), this implies that there is another point on the curve at which a vertical line would intersect multiple times (for instance, if it loops back over itself). Therefore, if the curve fails the vertical line test, it is not a function.
Given this description, the correct response is:
No, it fails the vertical line test.
