    Find the critical points by finding f'(x), which is9x2-9, or 9(x-1)(x+1). Equating this to zero, the valuesfor x are 1 and -1. These are the critical points (you wereright).
    The inflection points are found by finding f''(x). This is18x, and 0 makes this value 0, which is the inflection point.
