How to solve for concavity
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. WebMar 26, 2016 · For f ( x) = –2 x3 + 6 x2 – 10 x + 5, f is concave up from negative infinity to the inflection point at (1, –1), then concave down from there to infinity. To solve this …
