Web18. To determine the absolute maximum or minimum, consider the endpoints of the interval as well as the local extrema. This is because the absolute maximum or minimum may occur at the endpoints of the interval, or at a local extrema within the interval. We need to check all of these possibilities to find the absolute maximum or minimum. WebAbsolute Extrema Consider the function f(x) = x2 + 1 over the interval ( − ∞, ∞). As x → ± ∞, f(x) → ∞. Therefore, the function does not have a largest value. However, since x2 + 1 ≥ 1 … sls eclass https://oakleyautobody.net
