If f ' ( a) < 0 then f (x) is decreasing at x = a . Second derivative rule If f '' ( a) > 0 then f (x) is concave up at x = a . If f '' ( a) < 0 then f (x) is concave down at x = a . If f '' ( a) = 0 then don't use this rule! Graphs for the key derivative cases.

Using the First and Second Derivatives to Graph Function

WebFigure 1. Both functions are increasing over the interval (a, b). At each point x, the derivative f(x) > 0. Both functions are decreasing over the interval (a, b). At each point x, the derivative f(x) < 0. A continuous function f has a local maximum at point c if and only if f switches from increasing to decreasing at point c. WebNov 10, 2024 · The Second Derivative Test.

3.4: Concavity and the Second Derivative - Mathematics LibreTexts

WebJust as the first derivative is related to linear approximations, the second derivative is related to the best quadratic approximation for a function f. This is the quadratic function whose first and second derivatives are … WebThe second derivative is the rate of change of the rate of change of a point at a graph (the "slope of the slope" if you will). This can be used to find the acceleration of an … WebWhile the first derivative can tell us if the function is increasing or decreasing, the second derivative tells us if the first derivative is increasing or decreasing. If the second derivative is positive, then the first derivative is increasing, so that the slope of the tangent line to the function is increasing asxincreases. gold eagle proof coins for sale
