This is characterized by the concavity changing from concave down to concave up (as in function ℎ) or concave up to concave down. Now that we have the definitions, let us look at how we would determine the nature of a critical point and therefore its concavity.2.6: Second Derivative and Concavity Second Derivative and Concavity. Graphically, a function is concave up if its graph is curved with the opening upward (Figure 1a). Similarly, a function is concave down if its graph opens downward (Figure 1b).. Figure 1.

This tells you that f is concave down where x equals –2, and therefore that there’s a local max at –2. The second derivative is positive (240) where x is 2, so f is concave up and thus there’s a local min at x = 2.Tax calculators are useful for those who would like to know information about their take-home pay after deductions occur.

Using this we can see that the second derivative will be negative if \(t < 0\) and positive if \(t > 0\). So the parametric curve will be concave down for \(t < 0\) and concave up for \(t > 0\). Here is a sketch of the curve for completeness sake.Concavity and convexity are opposite sides of the same coin. So if a segment of a function can be described as concave up, it could also be described as convex down. We find it convenient to pick a standard terminology and run with it - and in this case concave up and concave down were chosen to describe the direction of the concavity/convexity.Working of a Concavity Calculator. The concavity calculator works on the basis of the second derivative test. The key steps are as follows: The user enters the function and the specific x-value. The calculator evaluates the second derivative of the function at this x-value. If the second derivative is positive, the function is concave up.we can therefore determine that: (1) By solving the equation: f '(x) = 0 ⇒ −2xe−x2 = 0. we can see that f (x) has a single critical point for x = 0, this point is a relative maximum since f ''(0) = −2 < 0.
