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. 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 …

WebJul 7, 2024 · Finding max/min: There are two ways to find the absolute maximum/minimum value for f (x) = ax2 + bx + c: Put the quadratic in standard form f (x) = a (x − h)2 + k, and the absolute maximum/minimum value is k and it occurs at x = h. If a > 0, then the parabola opens up, and it is a minimum functional value of f. WebNov 16, 2024 · Let’s take a look at an example or two.
