SpletConsider the function f(x) = x, on the domain 0 ≤ x < 1. The smallest value is f(0) = 0, which corresponds to the global minimum. However, there is no global maximum, as no matter how close a point is to x = 1, one can choose a point even closer that yields a larger function value. If the function was deﬁned on 0 < x ≤ 1, then it Splet1 Consider the function f(x) = xe−4x, 0 ≤ x ≤ 2.

Splet25. apr. 2024 · You find x = ± 1, y = z = 0. You then have the function, with the Lagrnge multiplier built in: x 2 + y 2 + z 2 − 1 ( z 2 + 2 y 2 − z 2 − 1) = − y 2 + 2 z 2 − 1. This evidently has a saddle point, not a maximum or minimum, at ( ± 1, 0, 0), so this choice does not work. Spletx = 1 6 is a local maximum because the value of the second derivative is negative.
