WebApr 3, 2024 · We also sometimes use the terminology that, when \(c\) is a critical number, that \((c, f (c))\) is a critical point of the function, or that \(f (c)\) is a critical value. The first derivative test summarizes how sign changes in the first derivative indicate the presence of a local maximum or minimum for a given function. WebExample. Suppose f : R n → R m is a function such that each of its first-order partial derivatives exist on R n.This function takes a point x ∈ R n as input and produces the vector f(x) ∈ R m as output.
