Determining the Intervals Over Which a Function is Positive
WebFinding the intervals where f ′ ( x) is positive (or negative), and hence where f ( x) is increasing (or decreasing) is closely related to critical numbers. Critical Numbers Recall that a critical number (also called a critical point) is a value of x where f is defined, and where f ′ ( x) is either zero or doesn't exist. WebLesson Worksheet: Increasing and Decreasing Intervals. In this worksheet, we will practice using the terms increasing, decreasing, and constant to describe the labeled intervals of a linear or nonlinear function graph. Which interval on the graph is decreasing? True or False: The graph is increasing over interval 𝐴 and decreasing over ... how do you write an introduction paragraph
