The first derivative is f'(x)=3x^2-6x and the second derivative is f''(x)=6x-6=6(x-1). The second derivative is negative when x<1, positive when x>1, and zero when x=1 (and of course changes sign as x increases "through" x=1). That means the graph of f is concave down when x<1, concave up when x>1, and has an inflection point at x=1.
