Unformatted text preview: f ( x ) on each of the intervals, and use the Test for Increasing and Decreasing Functions to determine whether f is increasing or decreasing on each interval. Lecture 18 8 ex. Given f ( x ) = x 3 3 2 x 2 6 x + 3. 1) Find all critical points of f . What are the coordinates of each point? Lecture 18 9 2) Find the open intervals on which f is increasing and decreasing. Lecture 18 10 3) Sketch the graph of f ( x ) = x 3 3 2 x 2 6 x + 3 Lecture 18 11 ex. The position of a particle is given by the function s ( t ) = t 3 9 t 2 + 24 t where t is measured in minutes and s ( t ) is measured in yards. When is the particle moving forward? When is it moving backwards? Lecture 18 12 ex. Consider the following graph of the derivative of a function f (so the graph is y = f ( x )). On what intervals is f increasing and decreasing?...
