WebAnswer: f (x) is concave up when x < −1/2 and concave down when x > −1/2. Let's solve this step by step. Explanation: Given that, f (x) = – (2x 3) – (3x 2) – 7x + 2 The first derivative of f (x): d/dx (–2x 3 – 3x 2 – 7x + 2) = −2 (3)x 2 −3 (2)x −7 = −6x 2 − 6x − 7 f' (x) = −6x 2 − 6x − 7 The second derivative of f (x): WebConcave downward, downward, is an interval, or you're gonna be concave downward over an interval when your slope is decreasing. So g prime of x is decreasing or we can say …
Concavity and Point of Inflection of Graphs
WebJerry Nilsson. In order for 𝑓 (𝑥) to be concave up, in some interval, 𝑓 '' (𝑥) has to be greater than or equal to 0 (i.e. non-negative) for all 𝑥 in that interval. The same goes for 𝑓 (𝑥) concave down, but then 𝑓 '' (𝑥) is non-positive. Can you use the third derivative to find inflection points?

WebConsider the following. (If an answer does not exist, enter DNE.) f(x) = ln(x2 + 7) Find the interval(s) on which f is concave up. (Enter your answer using interval notation.) Find … 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, ∞) . http://mathsfirst.massey.ac.nz/Calculus/Sign2ndDer/Sign2DerPOI.htm crypt roblox bedwars
