WebLet's see if we can use the derivatives to tell us that it is concave up: The first derivative is 2 x, which is always increasing. So the first derivative tells us the graph is concave up. The second derivative is 2, which is positive! So the second derivative test tells us that the graph is concave up. Both tests give us the correct answer! WebCalculus. Find the Concavity f (x)=x^3-12x+3. f (x) = x3 − 12x + 3 f ( x) = x 3 - 12 x + 3. Find the x x values where the second derivative is equal to 0 0. Tap for more steps... x = 0 x = 0.

Concave Up Graph & Function What is Concave Up? - Study.com

WebConcavity and convexity are opposite sides of the same coin. So if a segment of a function can be described as concave up, it could also be described as convex down. We find it convenient to pick a standard terminology and run with it - and in this case concave up and concave down were chosen to describe the direction of the concavity/convexity.
