Finding concave up and down.

We say this function f f is concave up. Figure 4.34(b) shows a function f f that curves downward. As x x increases, the slope of the tangent line decreases. Since the derivative decreases as x x increases, f ′ f ′ is a decreasing function. We say this function f f is concave down.

The sum of two concave functions is itself concave and so is the pointwise minimum of two concave functions, i.e. the set of concave functions on a given domain form a semifield. Near a strict local maximum in the interior of the domain of a function, the function must be concave; as a partial converse, if the derivative of a strictly concave ...

Concavity of Parametric Curves. Recall that when we have a function f, we could determine intervals where f was concave up and concave down by looking at the second derivative of f. The same sort of intuition can be applied to a parametric curve C defined by the equations and . Recall that the first derivative of the curve can be calculated by .

When the second derivative is negative, the function is concave downward. And the inflection point is where it goes from concave upward to concave downward (or vice versa). And 30x + 4 is negative up to x = −4/30 = −2/15, positive from there onwards. So: f (x) is concave downward up to x = −2/15. f (x) is concave upward from x = −2/15 on.Oct 20, 2023 ... f is concave up when x∈ f is concave down when x∈ Find the critical points c for the function f and apply the Second Derivative Test (if ...
