3.4: Concavity and the Second Derivative - Mathematics LibreTexts

WebWe call the graph below concave down. Figure 2 Definition of Concavity. Let f ' be the first derivative of function f that is differentiable on a given interval I, the graph of f is (i) concave up on the interval I, if f ' is increasing on I , or (ii) concave down on the interval I, if f ' is decreasing on I. WebWhen f ′ ′ ( x) is negative, f ( x) is concaving downward. Similarly, when f ′ ′ ( x) is positive, f ( x) is concaving upward. From the table, we can see that f ( x) is concaving downward within the interval of ( − ∞, 4). The function is concaving upward within the interval of ( 4, ∞) .

WebFor a rational function, you do have situations where the derivative might be undefined — points where the original function is undefined i.e. has zero in the denominator. Examples: f (x) = x³/ (x-5) at x=5 — asymptotic discontinuity in the function. g (x) = x (x+2) (x-3)/ (x+2) at x=-2 — point discontinuity in the function. Web1 de mar. de 2024 · So the graph is concave up in the interval 0 &lt; x &lt; 2. From 2 &lt; x &lt; 3 the graph is opening downwards. So the graph is concave down in the interval 2 &lt; x &lt; 3. For a smooth graph (do you know what this means?) an inflection point always lies between concave up and concave down segments.
