Graphing a function: 12. Consider the function f(x) = x3 (x - 2) and its derivatives: f' (2) = 723(7x -8) 28x - 8 f" (2) = 9x 3 What are the critical and inflection points of f? (i.e when is f', f" equal to 0 or undefined?) Use these to determine when f is increasing / decreasing and concave up /down
