How To Tell Where f (x) is Less Than 0 or Greater Than 0

WebOn the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f(x) = 5x + 1, then the slope is just 5 everywhere, so f'(x) = 5. Then f''(x) is the slope of a horizontal line--which is 0. So f''(x) = 0. See if you can guess what the third derivative is, or the ... WebAboutTranscript. Introducing intervals, which are bounded sets of numbers and are very useful when describing domain and range. We can use interval notation to show that a value falls between two endpoints. For example, -3≤x≤2, [-3,2], and {x∈ℝ -3≤x≤2} all mean that x is between -3 and 2 and could be either endpoint.

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. WebAbsolute Extrema. Consider the function f(x) = x2 + 1 over the interval ( − ∞, ∞). As x → ± ∞, f(x) → ∞.
