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.1 Sections 4.1 & 4.2: Using the Derivative to Analyze Functions • f '(x) indicates if the function is: Increasing or Decreasing on certain intervals. Critical Point c is where f '(c) = 0 (tangent line is horizontal), or f '(c) = undefined (tangent line is vertical) • f ''(x) indicates if the function is concave up or down on certain intervals.Some authors use "increasing" to mean "strictly increasing"; others use "increasing" to mean "non-decreasing". Unfortunately, that's not going to change on a time scale shorter than a human lifetime. In order to say a function is "increasing" in this sense, the domain must contain at least two points; it makes no sense to say a function is ...The function f ( x) = x 2 is a decreasing function in the interval ( − ∞, 0] and increasing in [ 0, + ∞).
