Concave interval calculator.
To determine concavity, analyze the sign of f''(x). f(x) = xe^-x f'(x) = (1)e^-x + x[e^-x(-1)] = e^-x-xe^-x = -e^-x(x-1) So, f''(x) = [-e^-x(-1)] (x-1)+ (-e^-x)(1) = e^-x (x-1)-e^-x = e^-x(x-2) Now, f''(x) = e^-x(x-2) is continuous on its domain, (-oo, oo), so the only way it can change sign is by passing through zero. (The only partition numbers are the zeros of f''(x)) f''(x) = 0 if and only ...
A concave function is also synonymously called concave downwards, concave down, convex upwards, convex cap, or upper convex. Definition [ edit ] A real-valued function f {\displaystyle f} on an interval (or, more generally, a convex set in vector space ) is said to be concave if, for any x {\displaystyle x} and y {\displaystyle y} in the ...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)).Whether it's to pass that big test, qualify for that big promotion or even master that cooking technique; people who rely on dummies, rely on it to learn the critical skills and relevant information necessary for success.

Short Summary. A relationship as shown by an equation or graph is concave up if the graph is gradually increasing in slope during some interval.
The fact that its derivative, \(f'\text{,}\) is decreasing makes \(f\) concave down on the interval shown. Figure 1.87 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. ConcavityDec 21, 2020 · Figure 3.4.5: A number line determining the concavity of f in Example 3.4.1. The number line in Figure 3.4.5 illustrates the process of determining concavity; Figure 3.4.6 shows a graph of f and f ″, confirming our results. Notice how f is concave down precisely when f ″ (x) < 0 and concave up when f ″ (x) > 0.
