Can a function have two absolute maximum
WebThe absolute extrema on an interval I, if it exists, is the number M ∈ R that satisfies ∀ x ∈ I, f ( x) ≤ M and ∃ x 0 ∈ I, f ( x 0) = M (in other words M = max { f ( x) ∣ x ∈ I } ). In your case I = ( 0, + ∞) (the function isn't defined at 0 ). We have ∀ x ∈ I, f ′ ( x) = − 1 x 2 < 0. Thus the function is decreasing. WebThe function has an absolute minimum over [0, 2), [0, 2), but does not have an absolute maximum over [0, 2). [0, 2). These two graphs illustrate why a function over a bounded …

WebNov 10, 2024 · The function in graph (f) is continuous over the half-open interval \([0,2)\), but is not defined at \(x=2\), and therefore is not continuous over a closed, bounded interval. The function has an absolute … WebDomain Sets and Extrema. Even if the function is continuous on the domain set D, there may be no extrema if D is not closed or bounded.. For example, the parabola function, f(x) = x 2 has no absolute maximum on the domain set (-∞, ∞). This is because the values of x 2 keep getting larger and larger without bound as x → ∞. By the way, this function does …

WebFeb 23, 2024 · The maximum value of the function is x = 2/3 and the maximum value is 25/3. Example 2: Determine the absolute maxima and minima of the function f ( x) = x 2 – 2 x + 5 on the interval [0,2]. Solution: The first step is to differentiate the function f (x) to find the critical point. f ′ ( x) = 2 x − 2. f ′ ( x) = 0.
WebOct 2, 2024 · 2.2: Absolute Value Functions. There are a few ways to describe what is meant by the absolute value x of a real number x. You may have been taught that x is the distance from the real number x to 0 on the number line. So, for example, 5 = 5 and − 5 = 5, since each is 5 units from 0 on the number line. the pickled goose bartonWebOkay, so we're asked to determine if it's possible to have more than one, then one absolute minimum.

The Extreme value theorem states that if a function is continuous on a closed interval [a,b], then the function must have a maximum and a minimum on the interval. This makes sense: when a function is continuous you can draw its graph without lifting the pencil, so you must hit a high point and a low point on that interval. the pickled herring bayfieldWebThe function has an absolute minimum over [latex][0,2)[/latex], but does not have an absolute maximum over [latex][0,2)[/latex].
