WebHowever, if we define ƒ on the closed interval [0, 1], then ƒ has a minimum at 0 and a maximum at 1. However, some functions do have maxima and / or minima on open intervals. For instance, let ƒ (x) = 1 - x² for x in the open interval (-1, 1). Then ƒ has a maximum at 0, but ƒ has no minimum. WebStart your trial now!

WebA continuous function f is defined on the closed interval 4 6.−≤ ≤x The graph of f consists of a line segment and a curve that is tangent to the x-axis at x = 3, as shown in the figure above. On the interval 06,< 0. WebFor example, consider the function f(x) = 1/(x2 + 1) over the interval (−∞, ∞). Since f(0) = 1 ≥ 1 x2 + 1 = f(x) for all real numbers x, we say f has an absolute maximum over (−∞, ∞) at x = 0. The absolute maximum is f(0) = 1. It occurs at x = 0, as shown in Figure 4.13 (b). powell methodist church powell tn
