How to solve for concavity
WebFor each interval between subcritical numbers in which the function f is defined, pick a number b, and then find the sign of the second derivative f ″ ( b). If f ″ ( b) > 0, then f ′ is … WebWe can use the Power Rule to find f" (x)=12x^2. Clearly f" (0)=0, but from the graph of f (x) we see that there is not an inflection point at x = 0 (indeed, it's a local minimum). We can also see this by thinking about the second derivative, where we realize that f" …

WebApr 24, 2024 · Graphically, it is clear that the concavity of \(f(x) = x^3\) and \(h(x) = x^{1/3}\) changes at (0,0), so (0,0) is an inflection point for \(f\) and \(h\). The function \(g(x) = … WebNov 30, 2005 · Suggested for: Finding Concavity of y = Integral from x to 0 The integral of (sin x + arctan x)/x^2 diverges over (0,∞) Mar 26, 2024 5 595 Volume integral of x^2 + (y-2)^2 +z^2 = 4 where x , y , z > 0 Mar 4, 2024 21 1K Finding f (x) from given f' (x) Jan 22, 2024 3 473 Find g (x)/h (y) for a given F (x,y) Feb 21, 2024 3 173
WebQuotient Rule In calculus, the quotient rule is a method of finding the derivative of a function that is the ratio of two differentiable functions. Let h (x)=f (x)/g (x), where both f and g are differentiable and g (x)≠0. The quotient rule states that the derivative of h (x) is hʼ (x)= (fʼ (x)g (x)-f (x)gʼ (x))/g (x)². http://mathonline.wikidot.com/concavity-of-parametric-curves

I tried this: Theme Copy f=fopen ('68 data set.txt'); c=textscan (f,'%f %f %f','CollectOutput',true); fclose (f); out=accumarray (c … WebStep 3: Analyzing concavity Step 4: Finding inflection points Now that we know the intervals where f f is concave up or down, we can find its inflection points (i.e. where the concavity changes direction). f f is concave down before x=-1 x = −1 , concave up after it, and is defined at x=-1 x = −1 . So f f has an inflection point at x=-1 x = −1 .
WebSolution: Since f′(x) = 3x2 − 6x = 3x(x − 2) , our two critical points for f are at x = 0 and x = 2 . We used these critical numbers to find intervals of increase/decrease as well as local extrema on previous slides. Meanwhile, f″ (x) = 6x − 6 , …
