If f prime is increasing is f concave up
WebIn general, the slopes of the tangent lines increase (from left to right) when the graph’s concavity is up. If the slopes of the tangent lines decrease (from left to right) then you most likely have a concave down graph. Using Derivative Tests to Show Concavity WebThe statement you are given is asserting that based on the value of $f'(c)$ alone, you can determine the concavity of a function. And this is not true , as Zev's example shows: He …

In calculus, we often encounter the concepts of concavity and inflection points, which describe the shape of a curve. Specifically, an interval of concave up refers to a section of a curve that is shaped like a cup and concave down refers to a curve shaped like an upside down cup. These intervals are important to understand in order ...

The second derivative test allows you to determine the concavity of a function by analyzing the behavior of the function's second derivative around inflexion points, which are points at which f^('') = 0. If f^('') is positive on a given interval, then f(x) will be concave up. LIkewise, if f^('') 8s negative on a given …
