Suppose that f(x, y, z) = 2x + 1y + 2z at which 0 ≤ x, y, z ≤ 2. 1. Absolute minimum of f(x, y, z) is 2. Absolute maximum of f(x, y, z) is Suppose that f(x, y, z) = (x − 3)² + (y − 3)² + (z − 3)² with 0 ≤ x, y, z and x + y + z ≤ 12. 1. The critical point of f(x, y, z) is at (a, b, c). Then a = b = C = 2. Absolute minimum of f(x, y, z) is and the absolute maximum is Suppose that f(x, y) = x² − xy + y² - 4x + 4y with x² + y² ≤ 16. 1. Absolute minimum of f(x, y) is 2.
