Lesson Explainer: Increasing and Decreasing Intervals of a …

WebA function f (x) increases on an interval I if f (b) ≥ f (a) for all b > a, where a,b in I. If f (b) > f (a) for all b>a, the function is said to be strictly increasing. x³ is not strictly increasing, but it does meet the criteria for an increasing function throughout it's domain = ℝ. 2 … Web26 apr. 2015 · Some authors use "increasing" to mean "strictly increasing"; others use "increasing" to mean "non-decreasing".
