For some reason, I can't see any new postings here. But thanks neilmac. And Caroline there's a standard investigative process that the student is taught. What are the Max, Min, asymptotes, symmetries of the function. Where does it cross the axes (roots), where is first derivative positive/negative, where is second derivate zero (points of inflection). That's a process of determining the properties that is gone through as a preliminary to drawing the graphs. Without it one doesn't have the basic information that allows the graph to be drawn. |
