First find the derivative: f' (x)=3x^2+6x+5. Next find the second derivative: f'' (x)=6x+6=6 (x+1). The second derivative changes sign from negative to positive as x increases through the value x=1. Therefore the graph of f is concave down when x<1, concave up when x>1, and has an inflection point when x=1.The second derivative of a function may also be used to determine the general shape of its graph on selected intervals.
