Next, we calculate the second derivative. \begin{equation} f^{\prime \prime}(x)=3 x^2-4 x-11 ... In this video lesson, we will learn how to determine the intervals of concavity (concave upward and downward), locate inflection points, and use the second derivative test to identify relative extrema.And the inflection point is where it goes from concave upward to concave downward (or vice versa). Example: y = 5x 3 + 2x 2 − 3x. Let's work out the second derivative: The derivative is y' = 15x2 + 4x − 3. The second derivative is y'' = 30x + 4. And 30x + 4 is negative up to x = −4/30 = −2/15, positive from there onwards.The Toyota RAV4 needs the coolant replaced every 40,000 miles under normal driving conditions. If you use the car for towing or frequently driven in stop-and-go traffic, the interv...Use a graphing calculator (like Desmos) to graph the function f. a. Determine the interval(s) of the domain over which f has positive concavity (or the graph is "concave up"). (2, 4) (3, 5): invalid interval notation b. Determine the interval(s) of the domain over which f has negative concavity (or the graph is "concave down").About. Transcript. Riemann sums are approximations of area, so usually they aren't equal to the exact area. Sometimes they are larger than the exact area (this is called overestimation) and sometimes they are smaller (this is called underestimation). Questions.

Now that we know the second derivative, we can calculate the points of inflection to determine the intervals for concavity: f ''(x) = 0 = 6 −2x. 2x = 6. x = 3. We only have one inflection point, so we just need to determine if the function is concave up or down on either side of the function: f ''(2) = 6 −2(2)First, recall that the area of a trapezoid with a height of h and bases of length b1 and b2 is given by Area = 1 2h(b1 + b2). We see that the first trapezoid has a height Δx and parallel bases of length f(x0) and f(x1). Thus, the area of the first trapezoid in Figure 2.5.2 is. 1 2Δx (f(x0) + f(x1)).

The ST segment is the flat, isoelectric section of the ECG between the end of the S wave (the J point) and the beginning of the T wave. The ST Segment represents the interval between ventricular depolarization and repolarization. The most important cause of ST segment abnormality (elevation or depression) is myocardial ischaemia or infarction.The second derivative of a function may also be used to determine the general shape of its graph on selected intervals. A function is said to be concave upward on an interval if f″(x) > 0 at each point in the interval and concave downward on an interval if f″(x) < 0 at each point in the interval. If a function changes from concave upward to concave downward or vice versa around a point, it ...Possible Answers: Correct answer: Explanation: The intervals where a function is concave up or down is found by taking second derivative of the function.

At inflection points, f′ f ′ has extrema. Thus, when given a graph of a function f f, if on the interval I I the graph is bent upward, so the slope of f f is increasing, it is concave up, if the graph ...Select the correct choice below and, if necessary, fill in the answer box to complete.
