On which intervals is f concave down
WebConcave up on (√3, ∞) since f′′ (x) is positive. The graph is concave down when the second derivative is negative and concave up when the second derivative is positive. … WebWhen f'' (x) is negative, f (x) is concave down When f'' (x) is zero, that indicates a possible inflection point (use 2nd derivative test) Finally, since f'' (x) is just the derivative of f' (x), …

WebFree Functions Concavity Calculator - find function concavity intervlas step-by-step WebTo find the interval of on which the function is concave down and concave up, first, we need to find the second derivative of the function using the power rule. Recall the rules below: if f"(x) is positive, then f is concave up. if f"(x) is negative, then f is concave down Solving the second derivative of the function f'(x)
WebDefinitions 1. Let f be a function and I be an interval. f is concave up on I iff its derivative f′ is increasing on I. f is concave down on I iff its derivative f′ is decreasing on I. ha,f(a)i … 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):

Answer:... solutionspile.com Web15 de out. de 2014 · #1 On which interval is the graph of f (x)=4x^ (3/2) - 3x^2 both concave down and increasing? A. (0,1) B. (0, .5) C. (0, .25) D. (.25, .5) E. (.25, 1) I found f' (x)=6x^1/2 - 6x and f'' (x)=3x^-1/2 - 6 I set f'' equal to zero and got x=.25 Also, I believe it is undefined at 0? Would the answer be C? I'm not sure where to go from here if it's not. H
