Figure \(\PageIndex{7}\). At left, a function that is concave up; at right, one that is concave down. We state these most recent observations formally as the definitions of the terms concave up and concave down. A function cannot be both concave up and concave down at the same time, and can only have one type of concavity at a particular point. To tell if a function is concave up or concave down at a specific point, you can look at the second derivative of the function at that point.

Inflection points are points where the function changes concavity, i.e. from being "concave up" to being "concave down" or vice versa. They can be found by considering where the second derivative changes signs. In similar to critical points in the first derivative, inflection points will occur when the second derivative is either zero or undefined.

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 ...Concave up or convex down describes an upward-opening curve or a curve that bends up into the shape of a cup, depending on which direction the curve opens or bends. The fact that concave down or convex up curves bend down or resemble a cap in shape distinguishes them. In other words, if the tangent’s slope rises as a result of an increase …Consequently, to determine the intervals where a function \(f\) is concave up and concave down, we look for those values of \(x\) where \(f''(x)=0\) or \(f''(x)\) is undefined. When we have determined these points, we divide the domain of \(f\) into smaller intervals and determine the sign of \(f''\) over each of these smaller intervals.If you evaluate the function at -1, for example, you would get a negative number, so it would be concave down less than 0.

So if a segment of a function can be described as concave up, it could also be described as convex down.You should get an upward-shaped parabola. Conversely, if the graph is opening "down" then it's concave down. Connect the bottom two graphs and you should get a downward-shaped parabola. You can also determine the concavity of a graph by imagining its tangent lines. If all the tangent lines are below the graph, then it's concave …

Walkthrough of Part A. To determine whether f (x) f (x) is concave up or down, we need to find the intervals where f'' (x) f ′′(x) is positive (concave up) or negative (concave down).
