Use the graph of f to estimate the local maximum and local minimum. A cubic graph is shown increasing, then decreasing, then increasing again. The graph intercepts the x axis at approximately -1.8, 0, and 3.2. Local maximum: approx. (-1,1.17); local minimum: approx. (2,-3.33) Local maximum: (0,0); local minimum: (3.2,0) Local maximum: ∞ local minimum: -∞ No local maximum; no local minimum
