When the second derivative of a function is positive then the function is considered concave up. And the function is concave down on any interval where the second derivative is negative. How do we determine the intervals? First, find the second derivative. Then solve for any points where the second derivative is 0. 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. Key Concepts. Concavity describes the shape of the curve. If the average rates are increasing on an interval then the function is concave up and if the average rates are decreasing on an interval then the function is concave down on the interval. A function has an inflection point when it switches from concave down to concave up or visa versa.Let's look at the sign of the second derivative to work out where the function is concave up and concave down: For \ (x. For x > −1 4 x > − 1 4, 24x + 6 > 0 24 x + 6 > 0, so the function is concave up. Note: The point where the concavity of the function changes is called a point of inflection.

If f'' (x) is positive on an interval, the graph of y=f (x) is concave up on that interval. We can say that f is increasing (or decreasing) at an increasing rate. If f'' (x) is negative on an interval, the graph of y=f (x) is concave down on that interval. However, as we decrease the concavity needs to switch to concave up at \(x \approx - 0.707\) and then switch back to concave down at \(x = 0\) with a final switch to concave up at \(x \approx 0.707\). Once we hit \(x = 1\) the graph starts to increase and is still concave up and both of these behaviors continue for the rest of the graph.May 27, 2022 ...

All polynomial characteristics, including polynomial roots (x-intercepts), sign, local maxima and minima, growing and decreasing intervals, points of inflection, and concave up-and-down intervals, can be calculated and graphed.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 ...Graphically, a function is concave up if its graph is curved with the opening upward (Figure 1a). Similarly, a function is concave down if its graph opens downward (Figure 1b). Figure 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.Second Derivative and Concavity.

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 …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.Question: Find the intervals for which the graph y=x3−6x2 is concave up and concave down. Identify the inflection points.
