"WebA closed interval notation is a way of representing a set of numbers that includes all the numbers in the interval between two given numbers. In this notation, the numbers at the endpoints of the interval are included in the set. The notation for a closed interval is typically of the form [a,b], where a and b are the endpoints of the interval. " - Find intervals where f x 0

WebMar 8, 2024 · The value of the interval is said to be increasing for every x < y where f (x) ≤ f (y) for a real-valued function f (x). If the value of the interval is f (x) ≥ f (y) for every x < y, then the interval is said to be decreasing. You can also use the first derivative to find intervals of increase and decrease and accordingly write them. Webf(x) = cos2 x−2sinx, 0 ≤ x ≤ 2π. (a) Find the intervals on which f is increasing or decreasing. Answer: To ﬁnd the intervals on which f is increasing or decreasing, take the derivative of f: f0(x) = 2cosx(−sinx)−2cosx = −2cosx(sinx+1). Since sinx+1 ≥ 0 for all x, we see that the sign of f0(x) is the opposite of that of cosx.
