Which graph represents the function f (x) = STARTFRACTION 2 x Over x squared minus 1 EndFraction? On a coordinate plane, a hyperbola and parabola are shown. The hyperbola has a curve in quadrants 1 and 2. The parabola opens down and has a vertex at (0, 0). On a coordinate plane, a hyperbola and a cubic functions are shown. They hyperbola has curves in quadrants 1 and 3, and the cubic function goes through (0, 0). On a coordinate plane, a hyperbola is shown. One curve is in quadrant 1 and the other curves goes through quadrants 2 and 4. On a coordinate plane, a hyperbola is shown. Both curves open downward in quadrants 3 and 4.
