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. 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. The point at (negative 1, 0.7), where the graph changes from moving downward with increasing steepness to downward with decreasing steepness is the inflection point. The part of the curve to the left of this point is concave down, where the curve moves upward with decreasing steepness then downward with increasing steepness. 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.Estimate from the graph shown the intervals on which the function is concave down and concave up.

Figure \(\PageIndex{1}\) This figure shows the concavity of a function at several points. Notice that a function can be concave up regardless of whether it is increasing or decreasing.Concave downward, downward, is an interval, or you're gonna be concave downward over an interval when your slope is decreasing. So g prime of x is decreasing or we can say …The function y = f (x) is called convex downward (or concave upward) if for any two points x1 and x2 in [a, b], the following inequality holds: If this inequality is strict for any x1, x2 ∈ [a, b], such that x1 ≠ x2, then the function f (x) is called strictly convex downward on the interval [a, b]. Similarly, we define a concave function.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.Then "slide" between a and b using a value t (which is from 0 to 1): x = ta + (1−t)b. When t=0 we get x = 0a+1b = b. When t=1 we get x = 1a+0b = a. When t is between 0 and 1 we get values between a and b. Now work out the heights at that x-value: When x = ta + (1−t)b: The curve is at y = f ( ta + (1−t)b )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.. If f′′(x)=0 and the concavity of the graph changes (from up to down or vice versa), then ….
