WebThe definitions for increasing and decreasing intervals are given below. For a real-valued function f(x), the interval I is said to be an increasing interval if for every x < y, we … WebA function is defined as the change in the output value with respect to the input where the output variable is dependent upon the input variable. Answer: Using the graph, the open interval on which the function is increasing is (-∞, -2) U (2, ∞) and decreasing in (-2, 2) interval. Also, there is no interval where the function is constant. WebExample: f(x) = x 3 −4x, for x in the interval [−1,2]. Let us plot it, including the interval [−1,2]: Starting from −1 (the beginning of the interval [−1,2]):. at x = −1 the function is … marjorie stoneman douglas high school shooter
