Review the graph of f(x). On a coordinate plane, a curve approaches x = negative 3 in quadrant 2 and approaches the x-axis. Another curve approaches x = negative 3 in quadrant 3, has inflection point (0, 0), and approaches x = 3 in quadrant 1. Another cure approaches the x-axis in quadrant 4 and approaches x = 3 in quadrant 4.

Which statement describes the behavior of the function around the vertical asymptotes?
