the answer is B or D. I mean both doesnt really matter which one. We can see that graph fallows cubic function pattern when x < 2 and option A is saying oposite (when x > 2). Option C cannot be the answer because there is graph when x is larger than 2 and that option doesnt define function when x is larger than 2.
