About Andymath.com Concavity 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. Calculus. Find the Concavity f (x)=x^4-24x^2. f (x) = x4 − 24x2 f ( x) = x 4 - 24 x 2. Find the x x values where the second derivative is equal to 0 0. Tap for more steps... x = 2,−2 x = 2, - 2. The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the ....
