To solve this problem we looked at the zeros (x&shy;interecpts) of the three functions. Then we looked to see if there was a corresponding function that had max or min values at the x&shy;interecpts. We noticed that where the green function crosses the x&shy;axis, the blue function has a max/min and that wehre the red function crossed the x&shy;axis the green function has a max/min. Thus, the green function is the derivative of the blue function and the red function is the derivative of the green function. So the original function, f, must be the blue graph, the first derivatve function, f', must be the green graph, and the second derivative function, f'', must be the red function.
