The graph of a function f is concave down when f ′ is decreasing. That means as one looks at a concave down graph from left to right, the slopes of the tangent lines will be decreasing. Consider Figure 3.4.1 (b), where a concave down graph is shown along with some tangent lines.

Dec 21, 2020 · 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.

In terms of the second derivative, we can summarize our earlier discussion as follows. The graph of y = f ( x) is concave upward on those intervals where y = f " ( x ) > 0. The graph of y = f ( x) is concave downward on those intervals where y = f " ( x ) < 0. If the graph of y = f ( x) has a point of inflection then y = f " ( x) = 0.David Guichard (Whitman College) Integrated by Justin Marshall. 4.4: Concavity and Curve Sketching is shared under a not declared license and was authored, remixed, and/or curated by LibreTexts. We know that the sign of the derivative tells us whether a function is increasing or decreasing; for example, when f′ (x)>0, f (x) is increasing.Second Derivative and Concavity. Graphically, a function is concave up if its graph is curved with the opening upward (Figure \(\PageIndex{1a}\)). Similarly, a function is concave down if its graph opens downward (Figure \(\PageIndex{1b}\)).. Figure \(\PageIndex{1}\) This figure shows the concavity of a function at several points. The concavity of a function/graph is an important property pertaining to the second derivative of the function. In particular: If 0">f′′(x)>0, the graph is concave up (or convex) at that value of x. If f′′(x)<0, the graph is concave down (or just concave) at that value of x. A Concave function is also called a Concave downward graph. Intuitively, the Concavity of the function means the direction in which the function opens, concavity describes the …Dec 21, 2020 · If we are trying to understand the shape of the graph of a function, knowing where it is concave up and concave down helps us to get a more accurate picture. Of particular interest are points at which the concavity changes from up to down or down to up; such points are called inflection points.

1) that the concavity changes and 2) that the function is defined at the point. You can think of potential inflection points as critical points for the first derivative — i.e. they may occur if f"(x) = 0 OR if f"(x) is undefined. An example of the latter situation is f(x) = x^(1/3) at x=0. (Note: f'(x) is also undefined.) Relevant links:

Find the intervals on which the graph of f is concave upward, the intervals on which the graph of f is concave downward, and the inflection points. f ( x) = - x 4 + 1 6 x 3 - 1 6 x + 2. From the table, we see that f has a local maximum at x = − 1 and a local minimum at x = 1. Evaluating f(x) at those two points, we find that the local maximum value is f( − 1) = 4 and the local minimum value is f(1) = 0. Step 6: The second derivative of f is. f ″ (x) = 6x. The second derivative is zero at x = 0.
