Answer to: Determine the intervals on which the following function is concave up or concave down. Identify any inflection points: f(x) = 2x^4 -...
Answer to: Determine the intervals on which the function is concave up or concave down. f ( x ) = \frac { 4 x } { ( 4 x ) ^ { 2 } + 27 } By...
Question: Find the intervals on which f is concave up, concave down, the points of inflection, the critical points, and the local minima and maxima.[Make a derivative chart.] f(x) = x^2 − 8x^1/2, (x >= 0) Find the ...
over intervals: , 3 2 , 3 2 , f 2 12 1 0 f 0 12 3 0 , interval , 3 2 3 2 , sign of f x Since f changes sign at the point where x 3 2 , 3 2 , 79 2 is an inflection point of f. b. The graph of f is concave up on 3 2 , and is concave down...
Consider a function f(x) which is differentiable, then the intervals can be determined where function is concave down and concave up. When the second derivative is strictly greater than zero, then f(x) is concave up and when the second deriva...

Answer to: Determine the open interval on which the graph g(x)= \frac{x^2 + 4}{25 - x^2} is concave upward or concave downward. By signing up,...
Improvement in skin texture and alleviation of the pigmentation in the concave area were observed in all cases during the 3–44-month follow-up intervals after the fat grafting, and softening of the hypertrophic scar was also observed as early as 1month after the fat grafting and continuously ...
On the interval (6,infinity) f' < 0 and the function is Decreasing.f" = 2x-4(x-9) and so f" = 0 at x=9; that's the Inflection Point.f" is negative when x < 9 (DOWNWARD concavity) and positive when x > 9 (UPWARD concavity)....
The estimator is also quite robust against modest deviations from the log-concavity assumption. We show that bootstrap confidence intervals for the value of the ROC curve at a fixed false positive fraction based on the new estimate are on average shorter compared to the approach by Zhou and ...
