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 ...

Check the second derivative test to know the concavity of the function at that point. What is a critical point in a function? A critical point of a function is a point where the derivative of the function is either zero or undefined. Let f(x) = √(x^3 + 4). Use a graphing calculator (like Desmos) to graph the function. Determine the interval(s) of the domain over which it has positive concavity (or the graph is concave up). Preview: Determine the interval(s) of the domain over which it has negative concavity (or the graph is concave down).1. Good afternoon. I am trying to find the concavity of the following parametric equations: x = et. y = t2e − t. I eventually got the second derivative to be 2e − 2t(t2 − 3t + 1). I then solved this equation for y=0 and got two inflection points ( x = 0.3819 and x = 2.6180 ). With numbers from this interval I get negative values, which ...For example, the function x2 x 2 takes the reals (domain) to the non-negative reals (range). The sine function takes the reals (domain) to the closed interval [−1,1] [ − 1, 1] (range). (Both of these functions can be extended so that their domains are the complex numbers, and the ranges change as well.) Domain and Range Calculator: Wolfram ...FIGURE 1. FIGURE 2. We can find the intervals in which the graph of a function is concave up and the intervals where it is concave down by studying the function's second derivative: . Theorem 1 (The Second-Derivative Test for concavity) If f00(x) exists and is positive on an open interval, then the graph of y = f(x) is concave up on the ...

So, for example, if the confidence level is 95%, the confidence coefficient is .95. The next step is to solve for α / 2. So, continuing with our example, we would have 1 - α = .95 and find the value of α / 2 to be .025. The most commonly used confidence level is ...

Concavity and convexity. For the analysis of a function we also need to determine where the function is concave or convex. In other words, we need to determine the curvature of the function. We say that a function f is concave on an interval ( a, b) if for all x ∈ ( a, b) f ″ ( x) < 0 . On the contrary, we say that a function f is convex in ...On the other hand, the midpoint rule tends to average out these errors somewhat by partially overestimating and partially underestimating the value of the definite integral over these same types of intervals. This leads us to hypothesize that, in general, the midpoint rule tends to be more accurate than the trapezoidal rule. Figure 3.

Find the value of x for which the curve shows relative maxima & relative minima. This is really simple if you watched videos. Find the first derivative of a function f (x) and find the critical numbers.The opposite is true when a curve is concave up. In that case, each trapezoid will include a small amount of area that's above the curve. Since that area is above the curve, but inside the trapezoid, it'll get included in the trapezoidal rule estimate, even though it shouldn't be because it's not part of the area under the curve.Find the open intervals on which f is concave up (down). Then determine the 3-coordinates of all inflection points of f. Your first two answers should be in interval notation.
