If a function is continuous, then absolute extrema may be determined … 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 for all real numbers x and x2 + 1 = 1 when x = 0, the function has a smallest value, 1, when x = 0.
