Find concave up and down calculator.
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.

Explanation: To find the intervals where a function is concave up and concave down, we need to examine the sign of the second derivative.Both sine and cosine are periodic with period 2pi, so on intervals of the form (pi/4+2pik, (5pi)/4+2pik), where k is an integer, the graph of f is concave down. on intervals of the form ((-5pi)/4+2pik, pi/4+2pik), where k is an integer, the graph of f is concave up. There are, of course other ways to write the intervals.And the inflection point is where it goes from concave upward to concave downward (or vice versa). Example: y = 5x 3 + 2x 2 β 3x. Let's work out the second derivative: The derivative is y' = 15x2 + 4x β 3. The second derivative is y'' = 30x + 4.

Use interval notation if you are asked to find an interval or union ... How do you find the intervals which are concave up and concave down for #f(x) = x/x^2 - 5#? How do you determine where the graph of the given function is increasing, decreasing, concave up, and concave down for #h(x) = (x^2) / (x^2+1)#? We always need to check on both sides of the inflection point to make sure we go from positive to negative or negative to positive. After this we can determine the intervals of concavity. Notice that at x = pi, the second derivative has value f''(pi) = -sinpi - cospi = 1, so we're concave up on the interval ((3pi)/4, (7pi)/4). The concavity changes at points b and g. At points a and h, the graph is concave up on both sides, so the concavity does not change. At points c and f, the graph is concave down on both sides. At point e, even though the graph looks strange there, the graph is concave down on both sides β the concavity does not change.

If f β²β²(x) < 0 f β² β² ( x) < 0 for all x β I x β I, then f f is concave down over I I. We conclude that we can determine the concavity of a function f f by looking at the second derivative of f f. In addition, we observe that a function f f can switch concavity (Figure 6). 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 state or the quality of a Concave function. For example, if the function opens upwards it is called concave up and if it opens downwards it is called concave down.

That means as one looks at a concave up graph from left to right, the slopes of the tangent lines will be increasing. Consider Figure 3.4.1 (a), where a concave up graph is shown along with some tangent lines. Notice how the tangent line on the left is steep, downward, corresponding to a small value of f β².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 \(f ...
