The maximum (small) value of the function ppt (Shanghai Education Edition) courseware

Mathematics: 3.4 "Maximum (Small) Value of Function" Problem 1 Function f (x) = x2. In (-∞, 0] is a subtractive function, in [0, + ∞) Increasing function. When x ≤ 0, f (x) ≥ f (0), when x ≥ 0, f (x) ≥ f (0). Thus x ∈ R, f (x) ≥ f (0) . Therefore, when x = 0, f (0) is the minimum value of the function value. Problem 2 The function f (x) = - x2 + 1. Similarly, we can see that x∈R has f (x) ≤f (0) . That is, when x = 0, f (0) is the largest value in the function.
