Web5 sep. 2024 · Suppose f is twice differentiable on I. Then f is convex if and only if f′′(x) ≥ 0 for all x ∈ I. Proof Example 4.6.2 Consider the function f: R → R given by f(x) = √x2 + 1. Solution Now, f′(x) = x / √x2 + 1 and f′′(x) = 1 / (x2 + 1)3 / 2. Since f′′(x) ≥ 0 for all x, it follows from the corollary that f is convex.

Web5. A function f is continuous and twice differentiable for all values of x. The figure above shows the graph of f ′, the derivative of function f on the closed interval [− 4, 2]. The … WebA function is said to be differentiable if the derivative of the function exists at all points in its domain. Particularly, if a function f (x) is differentiable at x = a, then f′ (a) exists … WebA differentiable function is a function whose derivative exists at each point in its domain. In other words, if 𝑥 = 𝑥 is a point in the domain, then 𝑓 is differentiable at 𝑥 = 𝑥 if and only if the derivative 𝑓 ′ ( 𝑥) exists and the graph of 𝑓 has a nonvertical tangent line at the point ( 𝑥, 𝑓 ( 𝑥)) . horse height measurement
