Note that this graph begins in Quadrant III and continues in Quadrant I. This is also the behavior of the odd function y = x^3. Thus, we can immediately eliminate the possibilities -18x^14 and 17x^12. The correct answer choice is 22x^9, as this, as y = x^3, has a positive coefficient and the same shape as the given graphed function for "large" values of positive or negative x.
