Finding where a function is increasing

WebDec 16, 2015 · According to the definition of an increasing function: f ( x): [ a, b] → R is increasing f ( x) < f ( y) ∀ x, y ∈ [ a, b] such that x < y So once you find out the function is increasing in the open interval ( a, b) by using differentiation criteria, then you can manually check that the conditions apply to the endpoints by showing that WebUsing a Graph to Determine Where a Function is Increasing, Decreasing, or Constant. As part of exploring how functions change, we can identify intervals over which the function is changing in specific ways. We say that a function is increasing on an interval if the function values increase as the input values increase within that interval.

WebCorollary 3: Increasing and Decreasing Functions Let f be continuous over the closed interval [a, b] and differentiable over the open interval (a, b). If f ′ (x) > 0 for all x ∈ (a, b), then f is an increasing function over [a, b]. If f ′ (x) < 0 for all x ∈ (a, b), then f is a decreasing function over [a, b]. Proof WebSorted by: 2.
