Web25 de out. de 2016 · Oct 25, 2016 f (x) = xln(x) is concave up on the interval (0,∞) Explanation: To start off, we must realize that a function f (x) is concave upward when f ''(x) is positive. To find f '(x), the Product Rule must be used and the derivative of the natural logarithmic function must be known: Web12 de abr. de 2024 · A concave downward interval can contain both increasing and/or decreasing intervals. Remember that the first derivative f’ f ’ gives us the rate of change of the function f f, which allows us to determine when f f is increasing, decreasing, or constant. WebExample 1. Find the inflection points and intervals of concavity up and down of. f ( x) = 3 x 2 − 9 x + 6. First, the second derivative is just f ″ ( x) = 6. Solution: Since this is never zero, there are not points of inflection. And the value of f ″ is always 6, so is always > 0 , so the curve is entirely concave upward. tsia board
