Webidentify the decreasing or increasing intervals of the function. Remember from page one of these notes that the vertex of a parabola is the turning point. That means the vertex … WebMar 8, 2024 · Solution: To find intervals of increase and decrease, you need to differentiate the function concerning x. Therefore, f’ (x) = -3x 2 + 6x. Now, taking out 3 common from the equation, we get, -3x (x – 2). To find the values of x, equate this equation to zero, we get, f' (x) = 0 ⇒ -3x (x – 2) = 0 ⇒ x = 0, or x = 2.

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 decreasing, it continues to decrease until about 1.2; it then increases from there, past x = 2 Without exact analysis we cannot pinpoint where the curve turns from decreasing to increasing, so let ...
