In this section, we also see how the second derivative provides information about the shape of a graph by describing whether the graph of a function curves upward or curves downward. Increasing/Decreasing FunctionsIf f′(a) > 0 f ′ ( a) > 0, this means that f f slopes up and is getting steeper; if f′(a) < 0 f ′ ( a) < 0, this means that f f slopes down and is getting less steep.The graph shows us something significant happens near \(x=-1\) and \(x=0.3\), but we cannot determine exactly where from the graph. One could argue that just finding critical values is important; once we know the significant points are \(x=-1\) and \(x=1/3\), the graph shows the increasing/decreasing traits just fine. That is true.Concavity introduction. Google Classroom. About. Transcript.
