- Test for concavity When the function, f (x), is continuous and twice differentiable, we can use its second derivative to confirm concavity. When f ′ ′ (x)> 0, the graph is concaving upward. When f ′ ′ (x) <0, the graph is concaving downward. When f ′ ′ (x) = 0, the graph has an inflection point.

Dec 21, 2020 · We now apply the same technique to \(f'\) itself, and learn what this tells us about \(f\). The key to studying \(f'\) is to consider its derivative, namely \(f''\), which is the second derivative of \(f\).

There are a number of ways to determine the concavity of a function. If given a graph of f(x) or f'(x), determining concavity is relatively simple. Otherwise, the most reliable way to determine concavity is to use the second derivative of the function; the steps for doing so as well as an example are located at the bottom of the page.
