WebFigure 1.84 A function that is decreasing on the intervals \(-3 \lt x \lt -2\) and \(0 \lt x \lt 2\) and increasing on \(-2 \lt x \lt 0\) and \(2 \lt x \lt 3\text{.}\) Subsection The Second Derivative. We are now accustomed to investigating the behavior of a function by examining its derivative. The derivative of a function \(f\) is a new ... WebThe derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.Because the derivative is zero or does not exist only at …
